Bug 29467 – gcc-3.3.1 Compiler generates infinite loop

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description SpanKY 2003-09-23 16:26:34 UTC]

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)

Created attachment 18222 [details, diff]
gcc-unsharing_lhs.patch

i'm re-compiling stuff now to double verify this

[Comment 2 SpanKY 2003-09-23 16:44:49 UTC]

actually here is the original patch from gcc:

[Comment 3 SpanKY 2003-09-23 18:02:48 UTC]

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!

Ok, added to 1.3 patch tarball, and commited.
