Current Behavior

We are consistently receiving the following error: munmap_chunk(): invalid pointer leading to .../linclust/sh: line 76: 2444 Aborted (core dumped) $RUNNER "$MMSEQS" "${ALIGN_MODULE}" "$INPUT" "$INPUT" "$RESULTDB" "${TMP_PATH}/aln" ${ALIGNMENT_PAR} leading to: "Error: Alignment step died" "Error: Search died"

Steps to Reproduce (for bugs)

file used: seqs.fasta (download seqs.txt from this issue, then change the file name extension to .fasta) command used: mmseqs easy-linclust seqs.fasta /tmp/mmseqs /tmp --min-seq-id 0.9 -c 1.0 --cov-mode 0
