@wiredfool Tests fails with segmentation fault on TestJ2kEncodeOverflow.test_j2k_overflow. Do we need to replace SIZE_MAX with INT_MAX there?

[homm]

By the way:

size_t size1 = SIZE_MAX;
unsigned size2 = SIZE_MAX;

printf("%p\n", size1);
printf("%p\n", size2);

0xffffffff
0xffffffffffffffff

[wiredfool]

The SIZE_MAX is fixed in the malloc check branch, so I'd leave it to that.

removed Jpeg2KEncode fix from this pr

The SIZE_MAX is fixed in the malloc check branch, so I'd leave it to that.

I'm still seeing warnings.

SIZE_MAX isn't in Jpeg2kEncode.c in master at all.

Woops. Looks like some problem with ccache or I just was not careful enough.
