I haven't found one, but you can use gdb, the only thing you've to do is 
to compile with -g and -gc (or you use gdc)

Thanks. Using only -g seems to work just fine on gdb 7.3

You can do it if you install a signal handler for sigsegv and use 
backtrace_symbols to construct a stacktrace. Or you can just run the program 
in gdb or turn core dumps on and use gdb to inspect the core dump. But the 
first solution won't require you to rerun the program or always run with core 
dumps enabled. It _is_ more work though, if you've never done it.

	catchsegv (part of glibc, so should be available on just about all
Linux distros...)
