I noticed that when I use "-analyze-config" option in scan-build-py, it behaves differently from original perl based scan-build.

For example, command:

$ scan-build -analyzer-config ipa=basic-inlining make

Will work without any issues on perl version of scan-build. But on scan-build-py it will throw an error message "error reading 'ipa=basic-inlining'". 
After debugging, it turns out that the scan-build-py does not put "-analyzer-config" flag in front of the analyzer config flags (in this case is the "ipa=basic-inlining") in the final clang command line. This patch fixes this issue.
