repro case
Using "clang version 3.1 (trunk 147866)", llvm-cov crashes with simple test
case:
To repro:
- uncompress attached file
- cd llvm-cov.crash
- edit the first line of the Makefile to provide the path to your llvm install
directory
- make
- make docov
- make crash
The llvm-gov process then reproducibly crashes as follows:
