>Description:
I have a program written in perl with ithreads that will randomly SIGSEGV. The multithreaded part starts
20 threads to download pages from websites. I have this backtrace from gdb:

#1 0x282b30fa in fgets () from /lib/libc.so.5

I'm sure that doesn't have enough information, as nothing has debug symbols turned on. If there's any more
information I can provide, I would be happy to. I set the priority to low, since I know this isn't a
production level feature.
