is the error still exactly the same as you had originally?
if this happens again, rather than deleting the build directly, can you just try to delete the xpatch.h.gch file
and then try to go live, and see if this fixes it.
also can you confirm it does it with all patches e.g. even the tutorial patches.
the issue is, this is not an axoloti bug as such, its the compiler crashing... so we need to determine what it is thats causing the compiler to crash.
whats obviously odd, is that it appears to be working for you, for months at a time, then suddenly stops...
so something must change... Im guessing its not something as 'obvious' as immediately after you upgrade Axoloti, as you would notice this... so its something outside of axoloti.
are others getting this regularly?
seems odd, johannes doesnt seem to get it... as he uses windows most of the time. (I dont)
