are You sure?

e.g some times ago we thought the gcc4 was buggy (konqs sigsegv issue).
finally there was a bug in konq's code:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19317#c32
so please don't blacklist 4.0.x tree. we should fix bugs.
blacklisting is like a hiding head in the sand.

i'll check this bug deeply in free time.
i think that some global-object-contructor causes sigsegv.
program enters into __do_global_ctor_aux and doesn't reach the main().

(gcc-4.0.1-20050507).

Pawel.
