[PATCH v2 0/1] MR8962: dbghelp: Fix pointer truncation issues when parsing 64-bit Mach-O binaries in a Wow64 process

[Brendan Shanks (＠bshanks)]

When running `SymInitializeW(GetCurrentProcess(), NULL, TRUE)` in a 32-bit EXE on 64-bit macOS, there are a number of syscall faults resulting from 64-bit pointers being truncated to 32 bits and then passed to `ReadProcessMemory()`. Fix these, mostly by widening variables to 64 bits.
