> Could you explain which part(s) of the logs lead you to believe the bug
is in GHC? The logs are huge, and I couldn't find any clues pointing at
GHC with a quick scan, but maybe I missed something.
Line 2962 of ghc-valgrind4.txt looks suspicious, but the purify log is
more precise, specifying this exactly:
[E] FIM: Freeing invalid memory in LocalFree {36 occurrences}
Address 0x00265650 points into a HeapAlloc'd block in unallocated
region of the default heap
Location of free attempt
LocalFree [C:\WINDOWS\system32\KERNEL32.dll]
IsValidLocale [C:\WINDOWS\system32\kernel32.dll]
