I am currently debugging a heap-use-after-free.

==16772==ERROR: AddressSanitizer: heap-use-after-free on address 0x0679a27e at pc 0x00c57ebb bp 0x005de524 sp 0x005de524
READ of size 2 at 0x0679a27e thread T0  
--STACK TRACE--

However, Asan gives the following information about where that memory was allocated and where it was freed:

0x0679a27e is located 510 bytes inside of 3443-byte region [0x0679a080,0x0679adf3)

What am I supposed to do with this kind of information? According to Asan, the memory wasn’t allocated by me and it was also not freed by me?
Is this a false positive?

I am using clang-cl on windows x86 if that’s relevant.
