I think the definition of _Unwind_GetCFA is ambiguous. It says "the
value of %rsp at the call site in the previous frame." GCC is
returning the value of %rsp at the point of the call to throw.

While I'll agree that something looks fishy, we can't tell what.
You don't actually know what the correct values are. You can guess
that they're wrong, based on the curious

My question was: why I get wrong (from my pov) CFA value from GCC unwinder.
I rewritten my small test.

RMS hasn't worked on GCC since 1991. He would just refer the question

Use _Unwind_GetIP here, for one.
In fact I'm not interested in IP or RA here, I need some conte

I got strange problem in LuaJIT [1] stack unwinding on Solaris x64.
If I build everything using GCC with unwinder from libgcc_s everything
works fine.
But when I try to use GCC-built libluajit.a in executable built using
Sun Studio 12.2 with standard solaris unwinder from libc I got a cr
