Follow-up Comment #7, bug #59093 (project make):

I don't like the idea of adding new variables to control stack limit sizes. 
That's just too esoteric for anyone who just wants to run  make to deal with. 
This should be invisible to users.

Given that the situation you have is not actually a large recursion of
functions, I looked at the implementation of filter/filter-out and it's just a
stupid implementation which is probably slow as well.

I've added a new patch that rewrites this to be smarter and not use lots of
stack.  Please remove the previous patches that try to reset the stack size,
and apply SV-59093-1.patch and see if that fixes your problem.

(file #50264)
