Debian and derivatives (some of which have since resolved this), Gentoo, and 
potentially --- I did not have direct testing access to any of those, so this 
is indirect based on googling of diffs --- some of RH/Fedora systems, for 
some periods of time (likely to be reverted now). GCC version is 4.0.x. The 
issue is use of an incompatible default allocator for the STL, which implies 
that if two dynamically linked objects were built on systems with and w/o a 
change, and they pass an STL container around (think of a function returning a 
vector --- aRts has those), destruction will crash. 
Mandriva and SUSE are compatible with FSF GCC.

I am not Zack or Aaron. No one cares about what I say ;-)
