--- Comment #4 from Thiago Jung Bauermann <thiago.bauermann at linaro dot org> ---
The problem is that the backtrace goes through internal details of glibc, so
the "up 10" command makes assumptions about the internal organization of glibc,
which is fragile.

Most of the time this checks out, but occasionally <hand wave>the inferior is
in such a state</hand wave> that the number of frames to reach main doesn't
match.

I am in the middle of fixing the testcase to go up the stack one frame at a
time and checking when it gets to main. Do you agree it's a proper fix?

I'll probably be able to post it by EOD today or tomorrow.
