When clang has bugs, it is common for it to crash unceremoniously. That said, if you know of a reasonable way to assert here before the crash, that'd be great. > The bad thing is that the same problem can be reproduced not only in > frontend, but also in opt tool.

One of the command-line options in this case is a hidden option, so this isn't especially surprising. > And Yaron is right, I need to mix several outputs in stdout. What should I do > in this case? What's the context? It may be worth investigating whether there are other ways to address your need. If you want to use -rewrite-map-file and -info-output-file in a testcase at the same time, see the documentation for '%t' in the TestingGuide for creating multiple temporary output files. http://reviews.llvm.org/D13128 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
