Potential GC problem on the 3.3 branch


Hi,

I've come across a weird problem on the 3.3 branch with a big C++ file, which 
seems to be GC-related. A workaround is to slightly bump the default 
parameters of the GC.

I'm not very familiar with the GC so I don't really know how to attack the 
problem. Could any GC specialist take a quick look when he has some time? 
(ok, I know, this is an oxymoron :-) I'd like to know whether it is really a 
GC problem and maybe have a few entry points to investigate.

See http://gcc.gnu.org/PR12252

More generally, are GC problems safely fixable on a release branch?
