I think this was fixed in the unwinder by
2009-04-04 Jakub Jelinek <ja...@redhat.com>
* unwind-dw2.h (_Unwind_FrameState): Add REG_UNDEFINED enum value.
* unwind-dw2.c (execute_cfa_program): Set how to REG_UNDEFINED
instead of REG_UNSAVED for DW_CFA_undefined.
(uw_update_context_1): Handle REG_UNDEFINED the same as REG_UNSAVED.
(uw_update_context): If RA column is REG_UNDEFINED, mark it as
outermost frame.
and the bug can be avoided in glibc by
Wed Jun 25 13:30:42 CEST 2008 - rguent...@suse.de
- Add patch to fix unwinding through clone for x86_64 and i386.
[bnc#290807, bnc#403464]
bnc#403464 contains useful links (that's bugzilla.novell.com), one
reference to PR36568 which contains a glibc patch.
