8.6.170 crashing on punch-in

hi
im trying to create a bug report for the following problem:
Adding a punch in/out to the range ruler, then pressing 8 to activate punch in/out crashes ardour.
This happens in new sessions with no plugins
I opened a terminal to run a debug session and arrowed up to an existing command, then edited the ardour version number (which was previously something like 8.1.101)
This was the output:
$ sh /opt/Ardour-8.6.170-dbg/bin/ardour8 --gdb

What does this mean and how to rectify it?
Many thanks
PS Ardour 8 has been great for me, Ive hardly had any problems for a while.

You’ve landed at the debugger prompt. Type run and hit Enter, recreate your crash, and type bt into the debugger prompt. This should (hopefully) give you a stacktrace that can be used to debug the issue.

Now type run , press enter, and get Ardour to crash. and then produce a backtrace thread apply all bt

Many thanks for the helpful advice :grinning:
