- Install LLVM for Windows snapshot build from [http://llvm.org/build](http://llvm.org/build) (SVN r291454, built on 9 January 2017 at the time of filing this). - Launch LLDB: lldb -O "p 42". - LLDB crashes. I've tracked the cause down to snapshot builds being built with a statically linked CRT (-DLLVM_USE_CRT_RELEASE=MT). When a startup script is given on the command line, lldb.exe creates a pipe, writes the script into the write end, wraps a stdio file around the read end, and gives the resulting FILE* to SBDebugger::SetInputFileHandle(). Unfortunately, since SBDebugger lives in liblldb.dll, with its own copy of the CRT, that handle is not valid there. Later, it tries to read from that handle, and... boom.
