--- Comment #1 from Uli Schlachter <psychon at znc.in> ---
AFAIR this was already reported on the mailing list some years ago and the
conclusion back then was "compiler bug". Any reason why you disagree with this?
At least, changing the optimisation level to make a segfault go away sound like
a compiler bug to me (or e.g. violation of aliasing rules, or something like
that, but why would that be specific to 32 bit software?).

Also:

> Problem: TeamViewer 12 and Adobe acroread 9.x and probably other closed source applications do not start anymore

This only happens with closed source software and only on x86 (so 32 bit)?!
Uhm...

Could someone come up with a self-contained test case with a free license (even
WTFPL would be fine with me)?
