I tried various demo from GFX and I have a problem. In the demo, where the option "GDISP_NEED_MULTITHREAD" must be enabled, program working only with optimization -O2, when I switch to -O0, program stop in unhadled exception in first mutex lock. Increase stack size not solve the problem. This happening in master branch, demo in branch 1.6 working with -O0 without problem
