[llvm-dev] [llvm-bugs] clang-cl randomly does not finish when invoked with showIncludes command line switch when building EPICS

Wed Apr 27 11:02:58 PDT 2016

>From the stack traces, it sounds like clang-cl got blocked writing to
stdout because msvc_depends.pl wasn't reading from the pipe. The first
stack trace shows the driver clang-cl process waiting on the child -cc1
invocation, and the second one shows a blocking write syscall. I don't
think there's any action for us to take here.

If your build system uses configure and make, you might have better luck
using the clang driver instead. It can also generate MSVC compatible object
files.
