Small backtrace tool?

Hi
Regarding this issue I'm woundering if anyone could give me a hint of 
when Linux is using "signal trampolines"? When reading in 
gdb/i386-linux-tdep.c large portion of it handles them but I can't get 
the kernel to generate them. Using a simple signal handler in my 
userspace test-app seems not enough.
