Given that the only programs which seem to be *practically* affected by this is our Emacs, and Firefox/Thunderbird/etc. (which we don't have yet), and using G_SLICE=always-malloc apparently affects performance, I don't think that would be an appropriate solution.

In theory we have mallopt, mallinfo, posix_memalign, memalign, and valloc. I guess we can skip mallopt and mallinfo since they are pretty seldomly used in user-provided malloc implementations. Memalign is an old, deprecated function, so I wonder why it's used at all. GSlice should use posix_memalign instead. Yaakov, is there an option to use posix_memalign rather than memalign? I just checked the glib source, and it does use posix_memalign if it's available. I was quoting a 2007 discussion when I said it was memalign that GSlice wanted to use. Anyway, that would be three extra pointers in the per_process structure, for memalig, posic_memalign, and valloc, and we could get rid of the `if (!use_internal) set_errno(ENOSYS);' in those functions and rather call the user provided functions then.

Yaakov, is there any chance that you could patch Glib to do the

emacs issue. It would affect any GTK application that provides its own
malloc rather than using Cygwin's malloc. (But emacs is probably the
only such application in the distro.)
Given that the only programs which seem to be *practically* affected
by this is our Emacs, and Firefox/Thunderbird/etc. (which we don't
have yet), and using G_SLICE=always-malloc apparently affects
performance, I don't think that would be an appropriate solution.
For now, I think you'll have to add a wrapper script.

It's memalign, or at least that's what it was in 2007. See

There was a long discussion about this on the Cygwin mailing list in
2007. The thread starts at

and did not resolve the issue.
While we're waiting for a good solution, I could quickly repackage
emacs-X11 so that it supplies a wrapper script that sets
G_SLICE=always-malloc before calling emacs-X11. If people think that's
a good idea, I should be able to do it later today.
