--- Comment #4 from Sebastian Huber <sebastian.huber@embedded-brains.de> ---
There exists a patch for this problem:
https://www.sourceware.org/ml/gdb-patches/2014-07/msg00012.html
It was not applied due to a problem with the StackGhost. On Linux you don't
observe these problems since here you have a special case in sparc-linux-tdep.c
to add the DWARF unwinder. As a user I think it is quite unsatisfactory that
GDB is broken on SPARC for all non-Linux systems with GCC 4.8 and above due to
a problem in the StackGhost.
