C++ exceptions are broken in FreeBSD with gcc-compiled code?

[Yuri]

I had some mixup of gcc versions so I got some false errors with system 
compiler.
System gcc-4.2.1 works ok, as well as all gcc-4.2.X

But the newest gcc-4.3.0 breaks.

Executable aborts:
Abort trap: 6

Stack trace in debugger is:

Program received signal SIGABRT, Aborted.

And shared libraries loaded correspond to this compiler.
