Assertion `mmap(__ag_high_shadow, (0xdfff0000fffULL), 0x1 | 0x2, 0x02 | 0x10 | 0x04000 | 0x20, -1, 0) != ((void *) -1)' failed.

The size mapped is defined by HIGH_SHADOW_SIZE, from line https://github.com/AFLplusplus/qemuafl/blob/master/qemuafl/asan-giovese.h#L45. Could anyone help to explain why it is so large?

Thank you for the explanation. So the shadow memory are calculated by the following equation: `Shadow = (Mem >> 3) + 0x7fff8000;` And the range of shadow memory are divided...
