Yep - this looks a lot the problem I had.
In my case (NetBSD) the culprit was the OS code which
sets up the stacks during thread creation and signal
handler invocation -- it got it wrong. (One has to think
twice if the user code is jumped to through a fake function
call return...)

Sorry, I don't follow glibc development. Are there threads
involved or other userland scheduling things as setcontext()?
(Btw, there are still alignment issues in gcc-3.4 which show up
with Ada. Was reported by John R. Shannon in the gcc mailing
list.)
best regards
Matthias
