I still cannot reproduce this using latest Emacs bzr, and no further
information was given, hence I am closing this report. Please reopen if
you still have problems.

Hi,

I'm reporting a second bug in cedet in emacs23 (and 24). When editing a
C file, semantic saves the symbol tables from the include files required
by the C file in a cache file in order not to process again these files
when a new instance emacs runs. Sometimes, it happens that semantic is
not able to get the value of a symbol from a file, and report the error
to the echo area. As the save process is a task done automaticly on
iddle, every minutes semantic reports an error on the echo area (which
is just annoying). In the CVS version of cedet, the problematic symbols
are still not proceeded, but it doesn't report an error (actually, the
symbol is just marked as bogus). This is done in the 1.53 revision of
the semantic-lex-spp.el file of the cvs version
(http://cedet.cvs.sourceforge.net/viewvc/cedet/cedet/semantic/semantic-lex-spp.el?view=log).
I provide a patch that follows this fix (without adding the other stuff
that just do nothing for the moment).

Moreover, I have a backtrace with an example of a symbol that semantic
can't handle well in file ctype.h (the one in /usr/include/), here is the output :

Error Writing Table: #<semanticdb-table ctype.h>
Save Error: "\"Error in macro \\\"name\\\"\"": /home/jonathlela/.emacs.d/semanticdb/!usr!include!semantic.cache

Precisely, the error occurs when calling
semantic-lex-spp-table-write-slot-value with value =

(("__exctype" (spp-arg-list (#1="name") 3728 . 3734) (EXTERN "extern" 3735 . 3741) (INT "int" 3742 . 3745) (symbol "name" 3746 . 3750) (semantic-list "(int)" 3751 . 3756) (symbol "__THROW" 3757 . 3764)) ("isalnum" (spp-arg-list ("c") 5853 . 5856) (symbol "__isctype" 5857 . 5866) (semantic-list "((c), _ISalnum)" 5866 . 5881)) ("isprint" (spp-arg-list ("c") 6123 . 6126) (symbol "__isctype" 6127 . 6136) (semantic-list "((c), _ISprint)" 6136 . 6151)) ("ispunct" (spp-arg-list ("c") 6168 . 6171) (symbol "__isctype" 6172 . 6181) (semantic-list "((c), _ISpunct)" 6181 . 6196)) ("isxdigit" (spp-arg-list ("c") 6304 . 6307) (symbol "__isctype" 6308 . 6317) (semantic-list "((c), _ISxdigit)" 6317 . 6333)) ("_tolower" (spp-arg-list ("c") 7099 . 7102) (semantic-list "((int) (*__ctype_tolower_loc ())[(int) (c)])" 7103 . 7147)) ("toupper" (spp-arg-list ("c") 6855 . 6858) (symbol "__tobody" 6859 . 6867) (semantic-list "(c, toupper, *__ctype_toupper_loc (), (c))" 6868 . 6910)) ("isspace" (spp-arg-list ("c") 6213 . 6216) (symbol "__isctype" 6217 . 6226) (semantic-list "((c), _ISspace)" 6226 . 6241)) ("isgraph" (spp-arg-list ("c") 6078 . 6081) (symbol "__isctype" 6082 . 6091) (semantic-list "((c), _ISgraph)" 6091 . 6106)) ("_CTYPE_H" (number "1" 1003 . 1004)) ("_ISbit" (spp-arg-list ("bit") 1504 . 1509) (semantic-list "(1 << (bit))" 1510 . 1522)) ("__toascii" (spp-arg-list ("c") 3665 . 3668) (semantic-list "((c) & 0x7f)" 3669 . 3681)) ("__tobody" (spp-arg-list ("c" "f" "a" "args") 5305 . 5320) (semantic-list "(__extension__             \\\n   ({ int __res;             \\\n      if (sizeof (c) > 1)            \\\n {              \\\n   if (__builtin_constant_p (c))           \\\n     {              \\\n       int __c = (c);            \\\n       __res = __c < -128 || __c > 255 ? __c : (a)[__c];        \\\n     }              \\\n   else              \\\n     __res = f args;            \\\n }              \\\n      else              \\\n __res = (a)[(int) (c)];            \\\n      __res; }))" 5325 . 5787)) ("isupper" (spp-arg-list ("c") 6258 . 6261) (symbol "__isctype" 6262 . 6271) (semantic-list "((c), _ISupper)" 6271 . 6286)) ("iscntrl" (spp-arg-list ("c") 5943 . 5946) (symbol "__isctype" 5947 . 5956) (semantic-list "((c), _IScntrl)" 5956 . 5971)) ("tolower" (spp-arg-list ("c") 6782 . 6785) (symbol "__tobody" 6786 . 6794) (semantic-list "(c, tolower, *__ctype_tolower_loc (), (c))" 6795 . 6837)) ("toascii" (spp-arg-list ("c") 7062 . 7065) (symbol "__toascii" 7066 . 7075) (semantic-list "(c)" 7076 . 7079)) ("__isctype" (spp-arg-list ("c" "type") 3500 . 3509) (semantic-list "((*__ctype_b_loc ())[(int) (c)] & (unsigned short int) type)" 3514 . 3574)) ("_toupper" (spp-arg-list ("c") 7166 . 7169) (semantic-list "((int) (*__ctype_toupper_loc ())[(int) (c)])" 7170 . 7214)) (#1# symbol "_tolower" 5177 . 5185) ("__isascii" (spp-arg-list ("c") 3593 . 3596) (semantic-list "(((c) & ~0x7f) == 0)" 3597 . 3617)) ("isdigit" (spp-arg-list ("c") 5988 . 5991) (symbol "__isctype" 5992 . 6001) (semantic-list "((c), _ISdigit)" 6001 . 6016)) ("islower" (spp-arg-list ("c") 6033 . 6036) (symbol "__isctype" 6037 . 6046) (semantic-list "((c), _ISlower)" 6046 . 6061)) ("isascii" (spp-arg-list ("c") 7027 . 7030) (symbol "__isascii" 7031 . 7040) (semantic-list "(c)" 7041 . 7044)) ("isalpha" (spp-arg-list ("c") 5898 . 5901) (symbol "__isctype" 5902 . 5911) (semantic-list "((c), _ISalpha)" 5911 . 5926)))

The error is raised when sym =

("name" symbol "_tolower" 5177 . 5185)

I don't know if someone can do something with these informations, but
still it may be a good starting point to fix the problem.
