I use Fortran powerstation. Although the code runs O.K. under "Debug" mode, there are strange mistakes occuring under "Release" mode. Has anybody met such situation?

Hi,

You should carefully check all the options you use in the release mode. In particular, the reordering of operations or the loop transformation can induce errors.

Thank! But why in "debug" mode, we cannot see the mistake?

Hi,

Usually in the debug mode you do not see the mistakes due to the optimizations simply because the optimisation options are turned off ;-)

You may try to use the release mode, increasing the number of compilation options asked for efficiency.

I think your compiler manual will be of great help to identify, and possibly turn off, which optimisation options are the most "agressive".

Good luck

Buch
