An attempt to bootstrap trunk on Windows XP currently fails here as

Doesn't happen to me, strangely.  But it could be borderline.

Like it says: enlarge the size of dumped_data[] array.

It happened to me. I guess it depends on the toolchain. I am using
msys2 64-bit with the latest updates.

Right. I made a change to src/w32heap.c (the value is arbitrarily chose):

- # define DUMPED_HEAP_SIZE (18*1024*1024)
+# define DUMPED_HEAP_SIZE (28*1024*1024)

then the build went through.

I see it, too.

Maybe we should double the value?

64-bit builds use a different size.

Arbitrary, indeed.  The value needs to be as small as possible,
because that's memory wasted in the dumped Emacs (because
bootstrap-emacs needs significantly more space in that array).  So I'd
appreciate if you or someone else could come up with a smaller
increment.  E.g., does 19 instead of 18 work?

I have just tried 19 and it works.

Thanks for the information.  Bumped to 19/12 MB.

Thanks.

dumped_data_commit: memory exhausted

[Richard Copley]

Building current emacs master with the current 64-bit MinGW-W64
toolchain from MSYS2 (gcc 6.2), on Windows 10, I get:

dumped_data_commit: memory exhausted

Increasing DUMPED_HEAP_SIZE from 20 to 21 in w32heap.c
lets the build succeed.

Cf.: http://lists.gnu.org/archive/html//emacs-devel/2015-05/msg00550.html

(Same symptom reported, and the resolution in that case was to
increase DUMPED_HEAP_SIZE from 18 to 19.)

When that happens, simply push a change that increases the value to a
safe level.  (I did it this time.)

Thanks.

Thanks Eli, and apologies, I don't have the privilege to push changes.

Silly me.  Sorry.

Don't let that stop you: just push harder!
