[Bug preprocessor/25799] New: [Regression 4.2] cc1 stalled with -O1 -fmodulo-sched

[drab at kepler dot fjfi dot cvut dot cz]

Attached code when compiled by gcc version 4.2.0 20060113 (experimental) using

----------
gcc -O1 -fmodulo-sched -c insmod.c -o insmod.o
----------

makes the cc1 (preprocessor) process stall indefinitely (well I let it few
minutes, then killed manually. Tested only on x86. It is a regression, since it
works with gcc version 4.2.0 20051224 (experimental). This bug may (or may not)
be related to the bug 25798 (same test file, simillar compile flags).
