Have you tried looking in "/usr/include" or "/usr/include/sys" for the
definitions!

Sig 11 is a segmentation violation (illegal memory access in a flat
32-bit VA space!) so your program has a bug.  You should be able to use
gdb to find the line of code that caused the error.  Eg.

# gdb geekthree geekthree.core
???> bt
