----------------------------+---------------------
 Hi,

 Currently I have a quite large GMl which needs to be parsed to geometry.
 When I run the attached query the Postgres db will crash.

 I've tested this in Linux (Centos), Windows 10 and Windows server.
 Everywhere the same crash. I've increased the work mem to 1 GB. increased
 the shared mem.

 Error log Postgres:
