[gs-devel] Check for the CPU stack size

[SaGS]

Hello all,

Recently I've seen some interest in updating/ tweaking the test procedure. 
Especially given the regression signaled in bug #688998 "Rev 7200 cannot 
start on Windows NT", I wonder if there would be interesting to include 
tests for the amount of CPU stack used/needed by Ghostscript.

I already have some Windows code that adds used stack info to the output 
produced by "-Z:". There's also an implementation for Linux, but I'm not a 
specialist there so maybe there's a better solution than mine. On other 
platforms, patched GS behaves exactly as without the patch. If you consider 
this would be helpful, I'll clean up the code and post it.

Note: By "stack used" I mean a reasonable estimate of the maximum stack ever 
used by the running instance, up to the moment it prints the information, 
and not the the stack size that's current when printing the info (which can 
be much smaller). Thus the final "... time ... memory ... stack = <NN>k" 
reflects the total stack size needed for processing the file(s)/ command(s) 
given.
