The AString::append methods for long, unsigned long and void *
pointers were using char arrays of 16 elements, which were not long
enough for 64-bit longs and pointers in __LP64__ systems. This
resulted in "FORTIFY_SOURCE: vsprintf: prevented write past end of
buffer. Calling abort()." when the
android.media.cts.DecoderTest#testFlush CTS test was run.
The AString::append methods that were using sprintf have been modifed
to use snprintf instead, taking the sizeof the "s" array (which has
been made 32 char without conditional compilation for __LP64__ where
appropriate), and checking the return value to ensure that the string
has not been truncated.
After this change and changes to the types of OMX_U32 and OMX_S32 in the
frameworks/native/include/media/openmax/OMX_Types.h header file, the
android.media.cts.DecoderTest#testFlush CTS test passes.
