[mpich-discuss] Debugging

[Gib Bogle]

Should I expect to be able to build an Intel Fortran debug executable on Windows?  When I do this 
with a program that runs in the release version, the debug version fails with an access violation. 
Also, should I be able to compile with lower optimization than /O3?  This same program (release 
version) runs with /O3 or /O2 but when it is built with /O1 an array subscript goes out of bounds.

Would valgrind be helpful?
