(In reply to Adriaan de Groot from comment #3)

I've been holding off a 13 upgrade as I was hoping some patches would make it
in to the tree so I could re-build my system, but I might just go forward with
the patches I need in a custom ports tree local branch and give it a go. I have
no sentimental attachment to 12.2, just no time to take the system down for the
rebuilds, and some long overdue backups prior to them. If yall are under 13 and
have no issues, works for me to try that as its the plan anyway to get there.
But if it is a 12.2 issue, and its resolvable, that would be cool too. It looks
like there is a nullptr being held potentially for the konsole window itself,
so maybe it is attaching tracking to process 0, theoretically the kernel? This
is beyond my level of understanding, or if process 0 would even be considered
the kernel. If you can give me some guidance on how to pull out that nullptr
using lldb to see what the structure is just give me an idea of how to find it

as to my Make.conf outside of setting westmere I have no CFLAGS nor CXXFLAGS
set, 
CPUTYPE?=westmere
###### CFLAGS+= -march=${CPUTYPE} -mtune=${CPUTYPE}
###### CXXFLAGS+= ${CFLAGS}
COPTFLAGS+= -O -pipe

obviously I have plenty of tweaks in my ports.conf portconf config, but nothing
crazy, and not much for kde, mainly media related, software synths, Atlas BLAS,
nvidia related, and such, none of which should affect konsole. As indicated
only kde hack is the qmake changes to make qt5-3d build non-AVX to let things
like pyside2 build and qgis. a few others to get openmpi and py-scipy as
referenced above by pr's
