I compiled this program with "ifort m.f90" then run it "./a.out", then error occured:
forrtl: severe (174): SIGSEGV, segmentation fault occurred
If I compiled it with "ifort m.f90 -CB" then No error occured
If I changed the 4th line into "integer::mn(3,3)" or just delete it, then compiled it with "ifort m.f90" No error occured.
This problem puzzled my a lot, is something wrong with my program?
my compiler is ifort version 14.0.3 on Mac OS
