Assertion failure in -fastx_uniques with -uc option

[PaulGreenfieldOz]

Assertion failures when running -fastx_uniques with -uc option. Most useful diagnostic is progress.cpp(496) assert failed: g_State == PS_Idle. Happens on both Windows and Ubuntu builds (20 & 22). fastx_uniques OK if .uc not specified (although sometimes slow, like when -uc specified).

Sample data file:
t_merged_t_dm_CC11A-CC_S7_L001_R1_001.zip

Thanks for the report.
I think the bug may be harmless because all output is successfully written?
Using -quiet option may avoid the bug.

[PaulGreenfieldOz]

Sorry, but the .uc file is created but empty. The fasta file is correct.

regards,
Paul

And using -quiet had no effect - still get assertion failure.

[rcedgar]

Ok. Suggest falling back to the binary for v11 https://github.com/rcedgar/usearch_old_binaries/

[PaulGreenfieldOz]

usearch11 works fine - but that doesn't help with migrating a pipeline to usearch12. For now, I'll just write my own derep code and move on.
