--- Comment #1 from Gijs Vermeulen gijsvrm@gmail.com --- This particular commit also causes backtraces to be broken. When you encounter a crash and click the "Close" button it will hang after this commit.
On current master it has evolved a bit. It now doesn't show any debug information and will just spam "013c:err:dbghelp_macho:macho_map_range map creation 0000016C failed 4 size 42944".
Maybe this can help narrow down the problem/help find a fix.
