hey @AndresFreundTec - I'm stuck getting PostGIS working with PG11 on Ubuntu Trusty. I've got a trace and I have no suspecions except that a gcc-built GEOS produces exception clang-built postgis can't catch. Can it be because of clang-3.9? Locally it's ok. https://github.com/postgis/postgis/pull/262#issuecomment-398558656 …
I don't think PGDG debian[ based] packages have switched to clang? Just checked the sources, and it's still the system default, which is gcc. FWIW, that backtrace doesn't have any trace of JITing. You could trivially test by just configuring jit=off before running the tests.
