Nice analysis! And nice patch too.
Rene himself said that he thinks we abuse obstacks in the current
implementation,
though I never took the time to figure out how to comb out the hair.
on head, I may experiment with adding an obstack_regrow macro that
I documented in the bug-m4 list.
That would be really interesting to see. Especially if it finds its way
back to glibc eventually :-)
Cheers,
Gary
