Status: Unconfirmed Owner: ---- Labels: Type-Bug Pri-2 OS-All Area-Misc New issue 9104 by craig.schlenter: compilation issues with gcc 4.4.0 on linux http://code.google.com/p/chromium/issues/detail?id=9104
I'm using the gcc and glibc from fedora 'rawhide' on fedora 9 to see if it catches interesting issues that older compilers don't see. This is intended to be a "tracker bug" with pointers to the actual issues since they may be in alternate issue trackers eg. skia, webkit etc. etc. Current issues: 1. Missing includes: http://codereview.chromium.org/46092/show 2. There is a truckload of strict aliasing issues of various flavours that show up when doing an opt build. I've only filed one bug so far: http://code.google.com/p/skia/issues/detail?id=18 There are more strict aliasing issues in: WebKit/WebCore/platform/text/StringImpl.h:199: warning: dereferencing pointer 'data' does break strict-aliasing rules WebKit/WebCore/platform/text/StringImpl.h:200: warning: dereferencing pointer '<anonymous>' does break strict-aliasing rules WebKit/WebCore/platform/graphics/skia/ImageBufferSkia.cpp:217: warning: dereferencing type-punned pointer will break strict-aliasing rules and so on. I'll post a full list after logging the issues in the relevant bugtrackers which is likely to be a slow process. Some interesting URLs for reading about strict aliasing: http://www.cellperformance.com/mike_acton/2006/06/understanding_strict_aliasing.html http://patrakov.blogspot.com/2009/03/dont-use-old-dtoac.html http://gcc.gnu.org/onlinedocs/gcc-4.3.2/gcc/Optimize-Options.html#index-fstrict_002daliasing-721 Compiling chrome in opt mode with -fno-strict-aliasing for the affected parts of the code does result in a working Hammer/chrome which is encouraging. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
