Gnu-malloc, which is used by default, calls brk() and sbrk(). The OpenBSD
man page says about these functions:
"The brk and sbrk functions are historical curiosities left over from ear-
lier days before the advent of virtual memory management."
So I thought it might be a good idea to try --with-system-malloc. But
with this option the build fails with the following output, after building
all .elc files and dumping xemacs two times.
The machine is a Sun Sparc10 running OpenBSD 2.3. The patches for getting
it to configure and build with gnu-make are posted to the list in another
mail. The XEmacs source used here are 20.1b40, but 20.4 gives very similar
(if not the same) results. Using the default gnu-malloc gives a working
XEmacs.
Does the OpenBSD malloc find a memory leak in XEmacs here, or is something
else broken? Does system-malloc work on other systems?
