-# define SHADOW_OFFSET (1ULL << 41)
+# define SHADOW_OFFSET (1ULL << 43)
On my ppc box which uses 44 bit address space this does not work:
% ASAN_OPTIONS=verbosity=1 ./a.out
|| `[0x100000000000, 0x3fffffffffff]` || HighMem ||
|| `[0x0a0000000000, 0x0fffffffffff]` || HighShadow ||
|| `[0x090000000000, 0x09ffffffffff]` || ShadowGap ||
|| `[0x080000000000, 0x08ffffffffff]` || LowShadow ||
|| `[0x000000000000, 0x07ffffffffff]` || LowMem ||
==36991== Shadow memory range interleaves with an existing memory mapping. ASan
cannot proceed correctly. ABORTING.
==36991== Process memory map follows:
...
0x0ffff4ad0000-0x0ffff4b00000 [stack]
Note:
0x0fffffffffff HighShadow
0x0ffff4b00000 [stack]
So, we need a bit more flexible solution.
