During warnings parsing, the gcc warnings are not correctly detected.
A gcc warnings is seen as an error and the build is set to failed (threshold set to 1 for error)
Note that it was working correctly with Hudson 308 and Warnings 2.8

I isolated the problem in gcc log file.
You can find attached :

• gcc log file
• 2 C++ file associated with the log

To reproduce the problem:

• Create a Job Free Style
• Copy in the workspace the three attached files
• Activate the Scan of Warnings on the log file

Results:

• An error is incorrectly detected and failing the build (instead of detecting a warning)
• By clicking on the detected error, the following exception is displayed:
