            Bug ID: 295787
           Summary: devel/qtcreator: hangs then killed due to memory
                    exhaustion
           Product: Ports & Packages

On FreeBSD 14.3-RELEASE-p14 amd64
KDE plasma6 desktop
Qt Creator 18.0.2 based on Qt 6.10.2

I can open creator and move around files but as soon as I modify anything
creator hangs. Often it block the desktop and will bring down other apps with
it.

Right now I'm trying to edit the minilzo-inl.c file, part of Valgrind. I want
to split line 3963. As soon as I hit enter creator hangs. It seems to be using
a huge amount of memory. dmesg contains things like

swp_pager_getswapspace(24): failed
swap_pager: out of swap space
swp_pager_getswapspace(5): failed
pid 72928 (qtcreator), jid 0, uid 1001, was killed: failed to reclaim memory


The callstack when it fails is here
