These are a bit different. g++ isn't at fault there: we are.

We turned on visibility for code that isn't supposed to use that. We 
should have used the pragmas in our headers and source files, instead of 
using -fvisibility=hidden.

In special, the hidden visibility was applied to Qt3 code, which doesn't 
support that in Unix. That meant the virtual tables and typeinfos for 
polymorphic classes without a destructor were emitted in the program and 
in libqt-mt. The end result is that dynamic_cast would operate wrongly.

The bug we're alluding to here is a real bug, affecting the g++ 3.4.x 
patched versions. See my other emails for details.
