4213	mc crashes on startup with subshell support as default in Freebsd	support.od.ua	andrew_b	"
At first I thought it was a problem in my version of the system and opened a [https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253831 ticket there].
After discussing crashdump, we think the problem is mc.

mc on the system can be run guaranteed with the `-u` option (--nosubshell). 

[https://mega.nz/folder/Qpxgwaxb#6QRwPG7A4s_AgswqUd5EKw Here] are the archives for the application mc (under FreeBSD) and crashdump mc.core. 

I am ready to provide additional information upon request.
