when adding weld to this after the geonodes stack we get a crash

steps to reproduce.

open file
add weld modifier to object in scene using extrude geonodes.

Looks like a somewhat recent issue as a build from the 17th seems to be fine.

ctx_loops_len and ctx_loops_ofs are both negative numbers inside the below stack
