Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

# This is a script used by some Buildbot buildslaves to push the project
# through Clang's static analyzer and prepare the output to be uploaded
# back to the buildmaster. You might find it useful too.
# Install Clang (you already have it on Mac OS X, apt-get install clang
# on Ubuntu, etc),
# or download checker at http://clang-analyzer.llvm.org/ and unpack it in
# /usr/local ... update CHECKERDIR as appropriate.

# You might want to do this for CMake-backed builds instead...
Disable static builds for static analysis. There's really no sense in analyzing everything twice, and this makes the job finish significantly faster.
