qt4 broken on i686

[Jan Rękorajski]

New builds of qt4 on i686 exhibit crashes (ex. linguist in avogadro), or
infinite looping (ex. meinproc4 in kde4-kig).

I'm running out of ideas[1] and time to troubleshoot this and would
appreciate if anyone would be willing to try and figure out WTF is
broken there.

[1] neither -O0, nor -std=gnu98 seem to do the trick, it could be a
glibc 2.34 issue, but I don't have resources at hand to validate it.
