Bug#269209: gcc-3.3: enters infinite loop building jpeg.c from libimage-exif-perl at -O2



Package: gcc-3.3
Version: 1:3.3.4-9
Severity: normal

Hi,

gcc-3.3 enters what seems to be an infinite loop while building the jpeg.c file
from libimage-exif-perl at -O2 (99% cpu usage, can sit there for hours without
any progress). This affects alpha, powerpc, s390 and sparc, according to the
buildd logs.

I can reproduce the problem on powerpc, attached are the preprocessed file and
a backtrace. Building at -O0 or -O1 works, as does building with gcc-3.4 or
gcc-3.2.

Thanks,

JB.
