Connector descriptions which are mention in coding. I will wait for the time because connector add checks all descriptions which are here with perfect essayshark. I start to do work for connector and make it more perfect.

The backtrace in the attached issue points to the match block parsing:

0   libsystem_c.dylib             	0x00007fff6acc7b44 strcasecmp_l + 92
1   libssh.4.dylib                	0x0000000107d27bbe ssh_config_get_match_opcode + 78
2   libssh.4.dylib                	0x0000000107d2608b ssh_config_parse_line + 763
3   libssh.4.dylib                	0x0000000107d25cfa ssh_config_parse_file + 266
4   libssh.4.dylib                	0x0000000107d40806 ssh_options_parse_config + 262
5   libssh.4.dylib                	0x0000000107d248e4 ssh_connect + 292

if you have some other crash report, please let us know.

Indeed. For the time being, I have opened the bug to follow the multipass issue, where I hope that this data shall be made available. In the meantime, proxyjump as in ProxyJump = myhost seems to be a trigger for the issue.

Without information about the libssh version, what configuration file was used (at least the offending match line), more verbose libssh logs (there is quite a lot of tracing logs around), it is hard to guess what went wrong with the parsing.
