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(). 2015-06-21 17:33:46 +02:00			`/**`
minimal fixes to visual test, so that it actually builds w/o warnings: - linux_process.c: add an SDLVisualTest_ScreenshotProcess() stub for linux builds succeed. - action_configparser.c: fixes -Wswitch warnings. - testharness.c: fixes 'is used uninitialized' warnings for userevents. - testharness.c: fixes format string argument to 'Force killing...' - testquit.c: fix type of options array in main(). - windows_screenshot.c: lowercase windows.h header name. - ran dos2unix on all sources and add missing newlines at files' ends. - minor adjustments to autotools build system (which actually seems to need more surgery for unnecessary stuff...) 2021-12-21 14:24:20 +03:00			`* \file mischelper.c`
