问题
I use a Fortran 90 model under Ubuntu 14.04. The gfortran 95 compiler (gfortran 4:4.8.2-1ubuntu6) and the gcc 4:4.8.2-1ubuntu6 are installed by Ubuntu Software Center. After I ran the model I get the following error message:
Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation.
Backtrace for this error:
#0 0x7F70C71AF7D7
#1 0x7F70C71AFDDE
#2 0x7F70C68EAD3F
#3 0x7F70C6EB6913
Could someone explain me what these backtrace codes mean? How can I handle these errors?
回答1:
Use the options -O -Wall -fcheck=all -g -fbacktrace during compilation and run the executable. If this does not provide the necessary information, try running your program under gdb and/or valgrind.
