[Bug target/31797] New: powerpc: race

["ralf_corsepius at rtems dot org" <gcc-bugzilla at gcc dot gnu dot org>]

When building RTEMS with gcc-4.2.0-20070430, gcc races on one file of the RTEMS
sources. It consumes up all available CPU time, gradually (very slowly) seems
consume all memory and doesn't seem to finish:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

This issue is reproduceable on i386-FC5 and FC6.
I would try to attach the *.i, but bugzilla refuses to let to do so, ATM. 

The same piece of code compiles fine with gcc-4.1.2 and older, so I am inclined
to call this to be a regression.
