[Bug optimization/14335] New: Infinite loop while compiling Sendmail with -ftracer

["r dot s dot a dot vandomburg at student dot utwente dot nl" <gcc-bugzilla at gcc dot gnu dot org>]

Compiling Sendmail's savemail.c with -ftracer causes gcc to enter an infinite 
loop, eating 100% CPU. Compiling without -ftracer works just fine.
