(In reply to Torfinn Ingolfsen from comment #0) Hi Torfinn, Thank you for your report. Are you able to run under the debugger and post a stack trace here? The easiest way to do this is: > sudo pkg delete libftdi1 urjtag && cd /usr/ports/devel/urjtag && WITH_DEBUG=yes make install > sudo pkg install gdb Then re-run the same urjtag command that crashes prefixed with /usr/local/bin/gdb and when it would crash type 'bt<Enter>' and post the stack trace here. Thank you, Yuri Here you go, one backtrace:

What version of libftdi do you have? A commit references this bug: Author: yuri Date: Wed Dec 2 21:05:56 UTC 2020 New revision: 556853 URL: https://svnweb.freebsd.org/changeset/ports/556853 Log: devel/urjtag: Add the NOASYNC option to possibly work around bugs like bug#251533 PR: 251533 Reported by: Torfinn Ingolfsen <tingox+freebsd@gmail.com> Changes: head/devel/urjtag/Makefile Torfinn, I added the new option NOASYNC to devel/urjtag. Could you please update this port, select this option (NOASYNC=ON), rebuild, and see if it still crashes? This option is not made user-choosable by urjtag, but they test if it is supported in libftdi and enable it internally. The code that crashes for you is conditional on this option.
