drrun segfault #37

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. I compiled DynamoRIO and DrMemory accoring to msandr/README.txt
2. For llvm I tool the release branch (3.3.1)
3. I compiled a simple hello world with -O1 -fsanitize=memory
4. Without drrun the binary runs fine
5. With drrun (with debug) I get:

Do I have to use a specific version of DynamoRIO with 3.3.1?

I didn't know whether I should ask here or at DynamoRIO. Also I couldn't find a 
memory-sanitizer mailinglist so I hope opening an issue is OK.

Did you try llvm trunk? This thing is very much in motion and compatibility 
with llvm releases in not a goal at this stage.

I just tried it again with the latest trunk and I get:
FATAL: Shadow memory range is not available.

This is only when run inside drrun. No error without drrun. Since I managed to 
compile all dependencies with MSAN I don't need drrun anymore and thus this 
issue isn't important to me anymore.
