ERROR: phylokernelnonrev.h:1034 && Numerical underflow for non-rev lh-derivative failed.

[IRSINGH27]

Hi, I was using the following version of iqtree software and the command. and this error keeps popping up irrespective if I specify the --seqtype or use the --safe argument. I have attached the msa file in tar.gz format
iqtree version - version 2.2.0-beta COVID-edition for Linux 64-bit built Mar 3 2022 built Mar 3 2022
iqtree command - nohup iqtree -s ./msa_rrna.fa --seqtype DNA -T 26 -B 1000 --safe 1>iqtree.stdout 2>iqtree_error.stderr&
msa_rrna.fa.tar.gz

Error: -

I recently had this same error on a large (~5000) tree build. Has there been any update? cc @iqbal-lab

I did not get any solution for this error, but I rolled back to the 1.6 version which is stable and then I did not faced this error.

Oh great, thanks for letting me know!
