Getting segmentation faults

[robe]

This might be just my computer not seeing the same issue on bots.

My pg log shows this

I tried against both mingw and VC++ build and I'm getting segmentation faults all over the place.

Anyway I'll investigate further - might just be something up with my pc.

I think it might be something screwy with my psql though because when I run the tests from pgAdmin works fine.

I'm guessing it's something wrong with my pg11 compile. pg10 seems fine aside from my usual issue with proj. will downgrade this issue as I'm sure its probably local to me.
