[squid-users] 2.3.S5 - Segmentation faults and 'dlmalloc' question

hi there,

is there any other possible reason for segmentation faults
with squid 2.3.stable5 than the known ones (gcc -O2) ?
i have compiled it using gcc 2.95.3 without the '-O' flags, but
squid seems to insist on quick segfault nearly each time i
use 'squid -k reconfigure'.

squid 2.3.stable5 (built from daily tarball 2001/10/29)

my compile options:

--enable-snmp \
--enable-cache-digests \
--disable-ident-lookups \
--enable-gnuregex \
--enable-time-hack \
--enable-dlmalloc

i have also tried building squid without dlmalloc and time-hack
but it wouldn't spare me from the segfaults.

i have also tried downloading a newer version of 'dlmalloc.c'
(v2.7.0) and putting it into the 'lib' directory of squid's source tree.
i have also placed the corresponding 'malloc.h' in the 'include'
directory - it compiles fine and everything works ok - except from
the sporadic segfaults.

the error msg in cache.log is:

FATAL: Received Segment Violation...dying.

any ideas?

ps: perhaps s.o. can help me out doing a debug trace, i never
did that before.
