If you are searching for undefined behaviour: Yes.
For real errors as in this case, recompiling and hoping that the
output is helpful seems much more difficult than running a
simulator that is known to cover exactly these cases.
This is not helpful, see "./configure --help" for instructions
invoking the various sanitizers for FFmpeg.
