My bug #17934 was merged with this one.
However, my test case demonstrates the problem WITHOUT threads.
The same issue appears with a single-threaded application of sufficient complexity.

Comment #32 in PR 17990 says:
In response to comment #30: it is libpthread's responsibility to align the
stack of subthreads properly. It doesn't do that, however, but I believe
that we have another PR for that (this is something that we can't really
do anything about, however).
This is the mentioned PR. The testcase in PR 17990 is the testcase from comment
#2 from this PR.
The default pthread library in RedHat 8.0 does align stack properly, as I am
able to trigger the bug. Testcase shows:
&x = 0xbffff9cc &s= 0xbffff9b0
&x = 0x4085fac8 &s= 0x4085faac
Should this bug be closed as WONTFIX?

Uros, did you mean "does *not* align the stack properly"? If so, I would
say yes, we should close the PR as WONTFIX, since we can't do anything
about it.

Ouch... RH 8.0 does _NOT_ align stack properly.
However, on second thought, is it worth to add some kind of -mforce-stack-align
parameter to gcc? Or maybe an attribute to the function? This way, one could add
a stack alignment code, similar to main() stack alignment:
pushl %ebp
movl %esp, %ebp
subl $8, %esp
andl $-16, %esp <- this
subl $16, %esp

An attribute could work. I doubt that a general flag would be useful,
since one in general doesn't know which functions are thread entry
points, so the compiler would have to emit such stack alignment code
into the prolog of each function it finds.
