Bug 3791 frysk-unwinder-update.patch
  http://sourceware.org/bugzilla/attachment.cgi?id=1491&action=view
sometimes could fail on:
fstack: ../../frysk/frysk-imports/lib/unwind/cni/FrameCursor.cxx:86: void
lib::unwind::FrameCursor::create_frame_cursor(jlong): Assertion `ip == offset +
proc_info.start_ip' failed.

That is correct as part of libunwind apparently supports nested functions but
the other part not:
ip=0xb2ee46,offset=0xc,proc_info.start_ip=0xb2ee30,buf="__pause_nocancel"
   969: 00b2ee30   101 FUNC    WEAK   DEFAULT   11 pause@@GLIBC_2.0
  4235: 00b2ee3a    20 FUNC    LOCAL  DEFAULT   11 __pause_nocancel
Currect:    offset=0xc,proc_info.start_ip=0xb2ee3a,buf="__pause_nocancel"
