================
Comment at: compiler-rt/test/hwasan/TestCases/heap-buffer-overflow.c:46
 //
-// CHECKm30: allocated heap chunk; size: 32 offset: 2
 // CHECKm30: is located 30 bytes to the left of 30-byte region
----------------
@kcc btw these checks rely on the fact that this allocation is not the first in its size class. This assumption can be broken even w/o llvm/compiler-rt code changes - ex. by a change in libc startup code.

Not sure what to do about this. Maybe we should also describe the chunk that we think is the source of the overflow (that would be an improvement regardless) and test for that.
