I had compiled apache sources with egcs 2.91.66 & was compiling mod_pmc.so
with gcc 2.95.2 & my LD_LIBRARY_PATH was somewhat misleading too. After compiling
both
Apache source & moudule sources by gcc 2.95.2 & fixing LD_LIBRARY_PATH, the
problem is still there
but here's the new strace o/p:
It is seg faulting on close(4) (4 is fd of mod_pmc.so) but why?
**PS I know this is mod_ssl list but no-one seems to be answering on
[EMAIL PROTECTED]
& this is sort of critical thing for us (Immediate customer requirement) , so plz
bear & help me..
Thanks.
