It may depend on the configure settings used to compile gcc.  Gentoo used t=
o=20
(or may still, but I think they changed this) use some faster memory=20
allocator by default with libstdc++ (not a Gentoo patch, just a different=20
configure selection) instead of the default slower memory allocator.

If the gcc devs had implemented it right that would have been fine but thei=
r=20
memory allocator didn't work in the presence of visibility support.  I=20
suspect something like that is going on here, you only trigger the bug in a=
=20
combination of certain circumstances.
