Hello,
I have made an attempt to track down the cause of this bug.
After
bzr revert -r 103045
Emacs builds when I configure it with
./configure --enable-checking=xmallocoverrun --with-ns CFLAGS='-g3 -O0'
After
bzr revert -r 103046
the error "temacs(74585,0x7fff70e01ca0) malloc: *** error for object 0x100768010: Non-aligned pointer being freed (2)" occurs during the call to "`/bin/pwd`/temacs --batch --load loadup bootstrap."
The changes made in revision 103046 are as follows:
