System: NetBSD saruman.ics.muni.cz 1.5S NetBSD 1.5S (SARUMAN) #21: Sat Feb 24 16:48:12 CET 2001 email@example.com:/usr/home/dolecek/soft/netbsd/sys/arch/i386/compile/SARUMAN i386
When I recently updated userland (I used some mid-February userland),
httpd started crashing when any LoadModule directive would be
used. I recompiled both httpd and modules in question couple
of times, so this should not be any versioning problem. Unfortunately,
I also upgraded httpd in between, so this MIGHT be caused
by some version mismatch.
on -current machine, LoadModule e.g. PHP4 module and see httpd
Don't know. I can provide stack backtrace upon request. Repeatably,
the program crashes within _rtld_symlook_obj(), obj->buckets
points to incorrect memory. When I look at obj contents,
couple of other structure members point to invalid (unmapped) memory.
This leads me to think this is really ld.elf_so issue. This MIGHT
be triggered by latest kernel changes (I have ~up-to-date kernel, too).
