debian has fixed this already, you can find the info here:
http://bugs.debian.org/cgi-bin/bugreport.cgi/gcc-unsharing_lhs.dpatch?bug=210848

basically gcc-3.3.1 generates an infinite loop under some circumstances ... some
good examples are things that use QT (i encounted this while upgrading to kde-3.1.4)

yeah, confirmed ... i had built QT with gcc-3.3.1-r3 and hit the infinite loop.

rebuilt gcc with the patch, rebuilt QT, and bam it all works again

Comment 4 Daniel Stone 2003-09-24 18:38:10 UTC

Yep, I can also confirm that this fixes; it definitely fixes up the problems on my 
Debian platform, and has now just done the same on Gentoo (once I convinced 
emerge not to stomp all over my shiny new -r3 ;). 
 
Cheers!
