Debugging
I wanted to try to figure out why AOLServer gets so large when generating
pages with a lot of data (when the CVS browser generates a large page the AOLServer binary can grow by 100MB or so -- not a great thing to have happen).
Anyway, I fired up GDB and was trying to figure out what was going
on and had no success at all. I could not even set a breakpoint...
It turns out that on gentoo (and some others, like Mandrake 9), libpthread is stripped which means GDB can't do anything useful when debugging threaded programs.
If you see
/lib/libpthread-0.10.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), strippedor get the error
Program received signal SIG32, Real-time event 32. 0x40163834 in pthread_getconcurrency () from /lib/libpthread.so.0when trying to debug a threaded program, then you will need to get an unstripped version of libpthread, or rebuild it on gentoo with
FEATURES="nostrip" emerge glibc
