[Message part 1 (text/plain, inline)]
The function absolute_filename() lib-src/etags.c has two invalid calls 
to strcpy() with overlapping arguments. It's undefined C that often 
happens to work, but breaks very badly for at least gcc 4.4.2 and glibc 
2.11 on x86_64, which is default for Fedora 12.

The attached patch replaces the bogus strcpy() calls with calls to 
memmove().
