Comment(by jorgearevalo):

 I don't really find the meaning of the three fist lines of
 "get_rt_context"

 rt_context ctx = 0;

 MemoryContext old_context;

 if ( ctx ) return ctx;

 As strk said, seems that ctx was a static variable sometime in the past,
 but now the third line has no sense.

 Pierre, did you find any problem with get_rt_context? Do you have a log?
 I'm trying to reproduce it before applying the suggested changes (make ctx
 static, replace palloc by malloc).
