Bug#1094137: testu01: autopkgtest regression: warning on stderr: pattern recipe did not update peer target 'fcoll-ltx-table-09.tex'.

Dear maintainer(s),

Your package has an autopkgtest, great. However, it fails since 
recently. Can you please investigate the situation and fix it? I copied 
some of the output at the bottom of this report. The test itself seems 
to pass, but there is a warning on stderr and by default that makes 
autopkgtest fail the test (unless the allow-stderr restriction is set).

The release team has announced [1] that failing autopkgtest on amd64 and 
arm64 are considered RC in testing.

More information about this bug and the reason for filing it can be 
found on
