Hmm, even with the pipe removed, I still have difficulty reproducing the crash within lit. I was doing:
C:\llvm\build>python ..\llvm\utils\lit\lit.py -v --no-progress-bar --param build_mode=Release tools\clang\test\Preprocessor\macro.c
But the test is passing. And the run line is simply:
// RUN: %clang_cc1 -E -x c %s

And, if I use the RUN line directly on a command-prompt, the test crashes as expected.
