When I compile my code using gfortran -g -fbacktrace -ffpe-trap=invalid,overflow,underflow File.f90 I get the following error:
Program received signal SIGFPE : Floating - Point exception - erroneous arithmetic operation.
Backtrace for this error:
#0 0x7f3da0768ed7 in ???
#1 0x7f3da076810d in ???
#2 0x7f3d9fe9b7ef in ???
#3 0x7f3da0230a3e in ???
My question is: how can I interpret these numbers and ???'s under "backtrace for this error:". How can I use this error message to help me find the error? Are they somehow related to the specific lines of code that are problematic? If so, how?
As of now I realize I have an erroneous arithmetic operation error but I have no idea where and this backtrace error message doesn't help at all. If I compile using just gfortran File.f90, there are no error messages at all during compilation or during running.
