Description
On Guix[1] we are currently hitting a bug when building ffmpeg@3.4.13 on i686, a CRC mismatch which happens when testing lavf.fits[2]. The bug does not occur on later ffmpeg versions (4.4.2, 5.1.4, 6.1.1 or 7.0.2) nor in version 3.4.13 on x86_64.
The CRC mismatched hash results seem to be reproducible on different machines for months now[3], regadless if build natively on i686 or on x86_64. So we are wondering if the CRC reference values are in need of update or if this reflects some hidden bug that affects i686 only.
The details for the CI build attempt can be found here[4], including a raw log[5] for the build failure and the libraries against which it was linked.
Here is a snippet for the failure:
