...alloc’d buffer that is one byte larger, and put a zero there. This doesn't seem to be working correctly, unless sys::Process::getPageSize() is returning the wrong thing for me. I'm getting here from getOpenFileImpl() in MemoryBuffer.cpp, which is deciding it's safe to mmap (by calling shouldUseMMap, where the page size check you mention is). The file is 561152 bytes, and the page size reports 16384, so this is not a multiple of page size (0x89000 & 0x3fff == 0x1000). Yet, the memory one byte past the mmap is not readable. >> There are three options here: >> >> 1. Remov...

In MemoryBuffer::init, we have an assert that reads the memory at `BufEnd`, which is one past the end of some memory region: from lib/Support/MemoryBuffer.cpp:45: > void MemoryBuffer::init(const char *BufStart, const char *BufEnd, > bool RequiresNullTerminator) { > assert((!RequiresNullTerminator || BufEnd[0] == 0) && > "Buffer is not
