Crash on structure with non-unique atom names

The following bug report has been submitted:
Platform:        Windows-10-10.0.18362
ChimeraX Version: 0.91 (2019-10-24)
Description
Running addh on this "structure" crashes ChimeraX.  I realize this is some gruesome 2D structure but still did not expect a crash.

The non-unique naming of the atoms in this large residue caused addh to generate 5-character hydrogen names. Switched to using hybrid-36 for numbers that would exceed the character limit.

These atom name character limits are going to plague ChimeraX forever into the future.  It would be a good move to use std::string and head-off this future burden trying to debug hard to fathom crashes.
