i686->arm cross gcc3.2.3 miscompilation of MICO.

[Karel Gardas]

Hello,

while playing with crosscompiling MICO on i686 host for
arm-unknown-linux-gnu platform, we have found some problems with stability
of resulting binary when it was compiled with -O2 or -Os. When we used -O0
everything was stable as it is on i686 (fyi: on i686 it's stable even
with -O2 - -Os is not tested yet).

I would like to ask if there is any known bug in gcc3.2.3 for arm platform
especially such causing miscompilation with -O2 and/or -Os. (I've looked
into bugzilla, but haven't found any).

Reason: if there is known, then I will not play with it. If not, then I'll
try to report more info and/or simplify it in my spare time.

BTW: I've not tried gcc3.3 since I'm using crosstools-0.10.0 which
contains some notes about broken combination of gcc3.3+glibc2.x.x (here
it's glibc problem)

Thanks,

Karel
