Subject: [Bug c++/50946] New: ICE on armhf with webkitgtk+
Date: Tue, 01 Nov 2011 19:55:00 -0000 [thread overview]
Message-ID: <bug-50946-4@http.gcc.gnu.org/bugzilla/> (raw)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50946
Bug #: 50946
Summary: ICE on armhf with webkitgtk+
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: konstantinos.margaritis@linaro.org
Created attachment 25677
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25677
minimal testcase produced using delta tool from
Source/WebCore/bindings/js/SerializedScriptValue.cpp in webkitgtk+
webkitgtk+_1.4.2-2 fails to build from source on Debian armhf due to a gcc ICE:
http://buildd.debian-ports.org/status/fetch.php?pkg=webkitgtk%2B&arch=armhf&ver=1.4.2-2&stamp=1311782209
Compiler originally used was g++ 4.6.1-10 but the same ICE appears with 4.6.2-3
(current Debian/unstable):

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions.
I used the delta package to produce a minimal testcase for the ICE
which I attach.
You can reproduce the ICE with g++ -O2 -fpermissive -Wfatal-errors -w
webkit_testcase-min.i.
The bug has also been reported to the Debian BTS:
