------- Comment #6 from pinskia at gcc dot gnu dot org 2006-11-24 00:17 -------
valgrind on the mainline shows begining with:
==11886== Invalid write of size 1
==11886== at 0x8592FE0: _cpp_lex_direct (lex.c:881)
==11886== Address 0x48DD485 is 5 bytes after a block of size 4,000 alloc'd
==11886== at 0x40051F9: malloc (vg_replace_malloc.c:149)
==11886== by 0x85AD1F5: xmalloc (xmalloc.c:147)
4.0.4 and 4.1.2 all have the same issue. I have not looked at 3.4.6 yet to see
if this is a regression.
