Could you post a simple test source file to reproduce it ?
And give the commands to compile and link it.
Thank you for your responses!
I've prepared simple test case, please download zip file from here:
It contains two directories:
"dll" has sources & scripts to build dll itself and test program (which uses the dll) by MinGW.
"test" has msvc project - test program which also uses same dll.
Additionally there are two files - configurations for gcc, used in compilation : specs, msvcr100.
In my MinGW installation they live in mingw\lib\gcc\mingw32\4.7.0\
First, run make in "dll" directory - it will produce:
Then open MS solution in "test" and build the project. It will produce msvc-exe.exe and will copy it to "dll" automatically.
As a result, "dll" directory will have:
Two exe files are the test programs which use the same mingw-dll.dll.
mingw-exe.exe always produce correct result (10 = 10).
msvc-exe.exe gives unpredictable output every time it runs (sometimes correct, sometimes not).
Everything is compiled with msvcr100 runtime.
I would really appreciate any advice and help in this direction, since I am stuck at this problem.
Thank in advance,
