Hello!
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

I wrote minimal test that reproduces the problem:

typedef struct _Unwind_Exception

void (*excleanup)(int, struct

Use _Unwind_GetIP here, for one.
In fact I'm not interested in IP or RA he
Any thoughts on this?
Or maybe it's wrong list for this question?

You've already had an answer from Richard Henderson, who is probably
the best-placed person to answer you.
My question was: why I get wrong (from my pov) CFA value from GCC unwinder.
I rewritten my small test.
$ cat main.c
#include

typedef

unwinder is right and libgcc_s one is wrong.
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.
Solaris is r
