Description David Warner 2025-12-03 13:10:19 UTC

flac 1.5.0 in Fedora 43 prints out large numbers of debug lines in the form
`FLAC__lpc_quantize_coefficients: negative shift=%d order=%u cmax=%f`
when encoding with certain parameters (specifically a small block size and the exhaustive model search option).

Example command line:
`flac -8e -f --blocksize 256 -o /dev/null input.wav`

This happens even when `--totally-silent` is provided.

The log itself seems to be just for debugging: https://github.com/xiph/flac/blob/9547dbc2ddfca06a70ea937dbb605bbe78ea5f90/src/libFLAC/lpc.c#L292

Can NDEBUG be set when compiling this package?

Reproducible: Always

Steps to Reproduce:
1. Encode file with small block size and high compression options, `flac -8e -f --blocksize 256 -o /dev/null input.wav`
Actual Results:
Lots of debug log lines.

Expected Results:
No debug log lines.

This was fixed recently for rawhide in bug ##2416751.

I'll submit a build for f43.

Comment 3 David Warner 2025-12-03 22:47:51 UTC

Thanks. Not sure why I couldn't find that earlier bug report - Google's results for 'FLAC__lpc_quantize_coefficients' are useless.
