segmentation fault help needed

I am porting a legacy fortran and C program from windows to linux. I was able to compile and link to get an executable but now the run fails with segmentation fault. 

forrtl: severe (174): SIGSEGV, segmentation fault occurred
Image              PC        Routine            Line        Source
hydro              0887AE70  Unknown               Unknown  Unknown
hydro              08099AD7  dsm2_init_                176  dsm2_init.f
hydro              08064EA1  MAIN__                    151  fourpt.f
hydro              08064ABA  Unknown               Unknown  Unknown

The failing call is getpid function from module use ifort. However when run with LD_DEBUG=all it complains about an unreferenced  symbol "scalable_malloc" right around the time it fails (see further below). Any help on how to tackle this would be great. Thanks
