            Bug ID: 34850
           Summary: llvm-rc tokenization error and crash with CMake
                    compiler tests
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: llvm-link

Created attachment 19244
  --> https://bugs.llvm.org/attachment.cgi?id=19244&action=edit
A zip file containing the stack trace, repro files, and unmodified manifest.

Not in the correct category, since llvm-rc has no category.

When trying to cross compile a project with cmake, cmake tries to see if
clang-cl works.
After I've set the variables that cmake needs, cmake fails to run the rc
compiler.
Having tested this myself on their file, llvm-rc outputs something along the
lines of "Invalid token found at position 2".
Looking at the source code it seems that it's missing tokenization for comments
in this format: /* comment */
After removing the comments llvmr-c crashes, giving me a stack trace.
I've included a repro case in the attachments, along with the stack trace
output and the original unmodified file (which contains an absolute path).

embed.manifest is an empty file
Execute as: llvm-rc reproN.rc /FO reproN.obj
Where N is the number of the repro file.
repro1.rc is for the tokenization error, and repro2.rc is for the crash.
manifest.rc is the original unmodified file.
