When I run a .exe file (Fortran code) the program hangs up at the end and gives a .exe.stackdump file. I read in the gdb guide what a stack is. Can I use only the .exe.stackdump file to debug the program? I tried gdb prog.exe.stackdump and it is not working. Do I have to run the program again in gdb and examine the stack? Thank you.
