OK, thanks, I can reproduce that problem on Fedora 17 x86-64,
by manually editing src/config.h so that it says
"#define GC_MARK_STACK GC_USE_GCPROS_AS_BEFORE".
My guess is that a GCPRO is missing somewhere. Ouch.
We won't detect that on typical hosts since GCPROs are noops.
There's a chance that GCPROs can be noops on AIX, too, so
please try what you did before, with the same patch and:
make distclean
./configure CPPFLAGS='-DDATA_START=0x20000000 -DDATA_SEG_BITS=0x20000000'
But then manually edit src/config.h to change this line:
#define GC_MARK_STACK GC_USE_GCPROS_AS_BEFORE
to this:
#define GC_MARK_STACK GC_MAKE_GCPROS_NOOPS
before you do "make".
I suppose we can look into the GCPRO business in the meantime.
I vaguely recall that there have been GCPRO bugfixes in the
trunk since emacs-24 was made -- perhaps backporting them
will fix this. What do you think, Glenn?
