I agree. The physmem heuristics patch is not safe enough to backport
for 3.2.x. Not only are we unsure of potential problems, but another
issue is that the patch relies on the --param interface to allow
tweeking the values. Backporting physmem + --param would be even more
destablizing. Without the --param ability, one couldn't manually
override the heuristics to ensure a given bug isn't related to GC
parameters.
We might want to consider bumping up the default hardcoded GC
values in 3.2.x. As in here (but not quite so big):
http://gcc.gnu.org/ml/gcc/2003-02/msg02002.html
E.g. we could bump up heapsize (last allocated) to 8M or 16M and
expand could be 1.4 or 1.5.
Thoughts?
