You might also need the patch mentioned further down in the same PR (PR 49738 comment 4). If it does not help, could you do the equivalent to the related PR 51103 comment 14, namely: Can you try to run this: /Users/inspirewong/Downloads/gcc-4.5.0/host-x86_64-apple-darwin10.8.0/gcc/f951 -quiet test.f where test.f contains: program foo real, parameter :: bar = sin (12.34 / 2.5) end program foo If it segfaults, please run it again inside gdb and try to get us a backtrace.
