I have fixed the bug via 95eb1de. Thanks a lot for your example. It would be almost impossible without proper test cases.
By the way, usually I wouldn't recommend to perform alignment (option -c) in the overlapping mode. First, this is much slower. Second, it introduces false overlaps. On pacbio C. elegans reads, doing alignment leads to a few more misassemblies.
I am closing this issue. If you the see same problem again, feel free to reopen it.

The display code from format.c:
195 void mm_write_paf(kstring_t *s, const mm_idx_t *mi, const mm_bseq1_t *t, const mm_reg1_t *r, void *km, int opt_flag)
196 {
197 s->l = 0;
198 mm_sprintf_lite(s, "%s\t%d\t%d\t%d\t%c\t", t->name, t->l_seq, r->qs, r->qe, "+-"[r->rev]);
199 if (mi->seq[r->rid].name) mm_sprintf_lite(s, "%s", mi->seq[r->rid].name);
200 else mm_sprintf_lite(s, "%d", r->rid);
201 mm_sprintf_lite(s, "\t%d\t%d\t%d", mi->seq[r->rid].len, r->rs, r->re);
202 if (r->p) mm_sprintf_lite(s, "\t%d\t%d", r->p->blen - r->p->n_ambi - r->p->n_diff, r->p->blen);
203 else mm_sprintf_lite(s, "\t%d\t%d", r->fuzzy_mlen, r->fuzzy_blen);
204 mm_sprintf_lite(s, "\t%d", r->mapq);
205 write_tags(s, r);
206 if (r->p && (opt_flag & MM_F_OUT_CG)) {
207 uint32_t k;
208 mm_sprintf_lite(s, "\tcg:Z:");
209 for (k = 0; k < r->p->n_cigar; ++k)
210 mm_sprintf_lite(s, "%d%c", r->p->cigar[k]>>4, "MIDN"[r->p->cigar[k]&0xf]);
211 }
212 if (r->p && (opt_flag & MM_F_OUT_CS))
213 write_cs(km, s, mi, t, r);
214 }
It seems a bit odd that it's mi->seq[r->rid].len instead of r->l_seq, when r->qs and r->qe are used.

This does seem like a minimap2 bug. However, I need your help to move further. Could you add the following lines to mm_write_paf():
if (!(r->rs < r->re && r->re <= mi->seq[r-rid].len)) {
fprintf(stderr, "%s <=> %s\n", t->name, mi->seq[r->rid].name);
abort();
}This essentially raises an assertion failure and prints out violating sequence pairs if coordinates are incorrect. By the way, there is no mm_reg1_t::l_seq. mi->seq[r->rid].len gets the reference sequence length. That part of code is correct.
Thanks!

Edit: More interesting is that this modification of minimap2 allows canu to continue because the offending lines don't appear in the output (even though the output is incomplete...).

Could you extract the sequence pair "370985" and "192001", or could you send me the two blocks? I have run minimap2 on some pacbio reads, but could not reproduce the issue on my dataset. Without the sequences that trigger the bug, it is quite difficult to fix it. Thanks.

This is weird. It's not failing when I run with just those two sequences, but it is for the whole block (both indexed and non-indexed). Anyway, here are the two sequences:

The entire indexed block can be found temporarily in my Dropbox code_scratch folder here. This index causes the issue when paired with the above highly-repetitive sequence.

Looking at the fix, does this mean that all reverse mappings were given the wrong ID? I'm just wondering if I should remap my sequences with the fixed minimap2.
