signed integer overflow at 'libavformat/avidec.c:1699'

Description

Summary of the bug:
Many FATE tests trigger signed integer overflow on big-endian FATE nodes such as 'ppc-linux-gcc-13.2-ubsan-altivec-qemu'.

The output looks similar to the following:

src/libavformat/avidec.c:1699:55: runtime error: signed integer overflow: 9223372036854775807 + 1 cannot be represented in type 'long long int'

As the PowerPC FATE nodes are currently the only big-endian representation we have, it is unclear if this is only particular to this configuration.

Fixed in 7a089ed8e049e3bfcb22de1250b86f2106060857. It was not due to endianness, but due to your system being 32bit.
