The eip register ("info registers") tells the currently executed machine
code address. Maybe you can find some function with its starting
address before that with "info symbol <address>".

Do you have all the libraries with debug information. If any of the
libraries crash and you don't have debug info, you will have a hard
time with after crash analysis.

Without a stack gdb cannot tell anything. The stack pointer and any
other register might be corrupted due to a corrupted stack. Try to set
breakpoints as short before the crash as possible and move step-wise
from those breakpoints onwards. Always remember the last position
before a crash as the position of another breakpoint before restarting.
