Hi,
 I just did a 'make bootstrap', emacs freezes but consumes 45% CPU and becomes non-responsive. I have build using GCC (MinGW) and running it on WXP.

Here is the back trace:

I continue, emacs window is white washed, I type C-g to get back initial screen and interrupt again to take a trace:

I feel the keyboard is not being read except for C-g sequence. I was building emacs with MSVC 2003 till yesterday and had to upgrade to MSVC 8 with which emacs does not build. I therefore decided to use GCC (MinGW) to build and started seeing these issues today (may not be related to GCC). I can switch back to MSVC 2003 as I have removed it!

I see the same thing.

I think this is not related to GCC. Jason did some changes to finally 
get the display update on w32 to work fast. I believe he is using MingGW.

Jason did his checkin just some hours before Dan N did his.

It looks like it could be Dan's changes that has broken something on w32.

The following change looks suspicious:

http://cvs.savannah.gnu.org/viewvc/emacs/src/term.c?root=emacs&r1=1.222&r2=1.223

Exactly what do you think is wrong there. It looks like Dan removed the 
test for MULTI_KBOARD and then just simplified the test for WINDOWSNT.

It's in fact a typo in this one:

http://cvs.savannah.gnu.org/viewvc/emacs/emacs/src/keyboard.c?r1=1.967&r2=1.968

It is fixed now.
