Hello,

My deepest apologies for trying to send such a mail, I should have 
thought about it first (sometimes, we are doing stupid things).

Anyway, I tried again with emacs-22.2 and the same problem occurs with 
approximatively the same backtrace, i.e:

#0  0x0026a17c in memcpy () from /lib/tls/libc.so.6

Here is only the relevant information (to me, the other information is 
clueless since the problem occurs during emacs build) you requested:

In GNU Emacs 22.2.1 (i686-pc-linux-gnu, X toolkit)
 of 2008-06-26 on lxhesf01
Windowing system distributor `The XFree86 Project, Inc', version 
11.0.40300000
configured using `configure  '--prefix=/tmp/esf_emacs-22.2/generated' 
'--exec-prefix=/tmp/esf_emacs-22.2/generated/libexec/emacs-22.2' 
'--mandir=/tmp/esf_emacs-22.2/generated/man' '--with-xpm' 'CFLAGS=-g 
-O2' 'LDFLAGS=

'CPPFLAGS=-I/tmp/esf_emacs-22.2/generated/work/emacs-22.2/xpm-3.4k ''

Important settings:

  value of $LANG: C

Hope this information will help.
Also note that the problem seems to appear randomly so you might have to 
run the installation several times if you need to reproduce the problem.


Thanks for your concern.

Pierre-Louis ESCOUFLAIRE
