Two vala-based ports, graphics/birdfont and productivity/minder, run out of memory when attempting to build them with this diff (and its previous version) on both amd64 and arm64: ***MEMORY-ERROR***: valac[93681]: GSlice: failed to allocate 2032 bytes (alignment: 2048): Cannot allocate memory Abort trap (core dumped) To be able to build birdfont with PORTS_PRIVSEP = Yes, I had to bump _pbuild's datasize-cur to 15G, while 14G was not enough. That's nearly double the current default. On amd64 without this diff, birdfont builds comfortably with a datasize-cur of 1G. birdfont may be easier to investigate since the error happens early in the build. You can get there relatively quickly by doing cd /usr/ports/graphics/birdfont doas pkg_add birdfont make FETCH_PACKAGES= prepare make Not sure if the top of the trace is of much use.
