I have an OpenMP code segment:
#pragma omp parallel for
for (i = 0; i < size; i++)
Built with mingw gcc 4.4.0. Run on Windows XP SP3, AMD 64 Athlon FX62 dual
core.
Run in an exe application it works fine, however when invoked as code in a DLL
the for loop threads do not increment properly and the loop runs infinitely
repeating the same values of i.
eg:
19 thread 0
26936 thread 1
20 thread 0
0 thread 1
21 thread 0
19 thread 1
22 thread 0
20 thread 1
21 thread 1
23 thread 0
22 thread 1
0 thread 0
23 thread 1
19 thread 0
24 thread 1
20 thread 0
