<pre>- Install LLVM for Windows snapshot build from <a href="http://llvm.org/build">http://llvm.org/build</a> (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.</pre>
