Hmmmm... Which OS version are you building this on? If it's 5.2.1-RELEASE, I think that libc_r.so.5 should be replaced by libpthread.so.N -- and one exceedingly annoying problem is that in a dynamically linked program like Apache, parts of it can end up being linked against libpthread, and other parts can be linked against libc_r, which will cause the whole thing to crash.
One solution is to use /etc/libmap.conf to substiture libpthread for libc_r during the dynamic link stage of program startup. See libmap.conf(5). /etc/libmap.conf should contain something like:
libpthread.so.1 libpthread.so.1 # Everything uses 'libpthread' libpthread.so libpthread.so
libc_r.so.5 libpthread.so.1 # Everything that uses 'libc_r' libc_r.so libpthread.so # now uses 'libpthread'
Of course, the ultimate solution is to fix all of the ports and recompile them so that they automatically link against the correct threading library.
Cheers,
Matthew
Hi Matthew,
I tried substituting libc_r with libkse (there is no libpthread on 5.2.1-RELEASE-p3). Still no good. httpd dumps core. :-(
I did an lsof for the httpd process (with php4 commented out) and it shows no sign of any two modules using different threading libraries:
# lsof|grep 76767|grep /lib|awk '{print $9}'
