Which gcc version? 

Does the problem go away if command line options -fomit-frame-pointer
or/and (possibly some other one) is removed?

If You're using gcc-3.0, 3.0.1 or 3.0.2 then please try gcc-3.0.3 as earlier
gcc-3.0.X versions had problems with option -fomit-frame-pointer
(PR#4529, PR#4763 and maybe some others in GCC GNATS database)
