Hi All,
Red Hat has access to the Coverity static analyzer, a checking system that
looks for coding errors. Attached is the coverity scan for the current libfpm
source code in Fedora 19. There are some errors in the generated SWIG code
(libpfm-4.3.0/python/src/*.c) that not much can be done for. There is a
dictionary of coverity errors available from:
