Libs don't matter, but please compile with debug info (either compile
with --enable-debug or add -g to cflags - either through manually
hacking config.mak or via --extra-cflags=-g2)
Also the documentation describes how to get some disassembly etc.
Also valgrind gives more information, if it crashes in gdb there it
really ought to crash at the same place in valgrind...
