Crash in PNS::LOGGER::Log (was: Crash while routing differential pair and switching layers)
Description
Still using the project in issue #8514 (closed), I got a third crash.
Here is the backtrace:

This time, I removed all the track segments for the differential pair shown in #8538 (closed), before rerouting from the same microvia. When the rerouting was completed, I believe I pressed "+" (don't ask me why), and got the crash.
I did an "export TOM_EXTRA_DEBUG=1" before compiling, in case this should make any difference.
