Bug 27468

Created attachment 33121 [details] Full transcript from WebCoreGenerated project After <http://trac.webkit.org/changeset/46060> a number of people at Apple are seeing an error during WebCoreGenerated that causes WebCore to fail to build. Some relevant snippets from the build log are as follows (a more complete log is attached): 16>Creating hashtable for /home/Jessie/OPENSO~1/WebCore/bindings/js/JSRGBColor.cpp 16>bison -d -p cssyy /home/Jessie/OPENSO~1/WebCore/css/CSSGrammar.y -o CSSGrammar.cpp 16>if sort /home/Jessie/OPENSO~1/WebCore/css/CSSPropertyNames.in /home/Jessie/OPENSO~1/WebCore/css/SVGCSSPropertyNames.in | uniq -d | grep -E '^[^#]'; then echo 'Duplicate value!'; exit 1; fi 16>touch CSSGrammar.cpp.h 16>touch CSSGrammar.hpp 16>echo '#ifndef CSSGrammar_h' > CSSGrammar.h 16>Invalid switch. 16>cat /home/Jessie/OPENSO~1/WebCore/css/CSSPropertyNames.in /home/Jessie/OPENSO~1/WebCore/css/SVGCSSPropertyNames.in > CSSPropertyNames.in 16>echo '#define CSSGrammar_h' >> CSSGrammar.h 16>cat CSSGrammar.cpp.h CSSGrammar.hpp >> CSSGrammar.h 16>perl "/home/Jessie/OPENSO~1/WebCore/css/makeprop.pl" 16>echo '#endif' >> CSSGrammar.h 16>rm -f CSSGrammar.cpp.h CSSGrammar.hpp 16># Lower case all the values, as CSS values are case-insensitive 16>gperf -CDEot -L ANSI-C -k '*' -N findColor -D -s 2 /home/Jessie/OPENSO~1/WebCore/platform/ColorData.gperf > ColorData.c 16>perl -ne 'print lc' /home/Jessie/OPENSO~1/WebCore/css/CSSValueKeywords.in /home/Jessie/OPENSO~1/WebCore/css/SVGCSSValueKeywords.in > CSSValueKeywords.in 16>if sort CSSValueKeywords.in | uniq -d | grep -E '^[^#]'; then echo 'Duplicate value!'; exit 1; fi 16>gperf -CEot -L ANSI-C -k "*" -N findDoctypeEntry -F ,PubIDInfo::eAlmostStandards,PubIDInfo::eAlmostStandards /home/Jessie/OPENSO~1/WebCore/html/DocTypeStrings.gperf > DocTypeStrings.cpp 16>Duplicate value! 16>make: *** [CSSValueKeywords.h] Error 1 16>make: *** Waiting for unfinished jobs…. A few interesting lines jump out: 16>Invalid switch. 16>Duplicate value! This doesn't reproduce on the build.webkit.org build bot in a clean build so it may be in some way related to the differences between the Debug_Internal and Debug configurations.
