Hello,

For the reported:
==10523== Conditional jump or move depends on uninitialised value(s)
==10523==    at 0x530FA72: GetDIBits (dib.c:1248)
==10523==    by 0x496AFE6: test_dibsections (bitmap.c:542)
==10523==    by 0x4990928: func_bitmap (bitmap.c:5629)
==10523==    by 0x49EBCE4: run_test (test.h:584)
==10523==    by 0x49EC0D3: main (test.h:654)
==10523==  Uninitialised value was created by a stack allocation
==10523==    at 0x496A45A: test_dibsections (bitmap.c:415)

I've just sent the patch:

Cheers;
Marc

PS: the line in GetDIBits has changed, it is now:
