Testing now with 3.4rc1 I'm running into a similar break even on x86_64: Entering /build/src/build/helpcontent2/source/text/shared/guide /build/src/build/swext/mediawiki/build.xml:79: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds Compiling: sdext/source/minimizer/informationdialog.cxx R=/build/src && S=$R/build && O=$S/solver/340/unxlngx6.pro && W=$O/workdir && mkdir -p $W/ComponentTarget/svl/util/ && xsltproc --nonet --stringparam uri 'vnd.sun.star.expand:$OOO_BASE_DIR/program/libsvllx.so' -o $W/ComponentTarget/svl/util/svl.component $S/solenv/bin/createcomponent.xslt $S/svl/util/svl.component [ build CHK ] svl R=/build/src && S=$R/build && O=$S/solver/340/unxlngx6.pro && W=$O/workdir && mkdir -p $W/Module/check/ && touch $W/Module/check/svl [ build DEP ] SRS:svl/res [ build SRS ] svl/res R=/build/src && S=$R/build && O=$S/solver/340/unxlngx6.pro && W=$O/workdir && mkdir -p $W/Dep/SrsTarget/svl/ && cat $W/Dep/SrsPartTarget/svl/source/misc/mediatyp.src.d $W/Dep/SrsPartTarget/svl/source/items/cstitem.src.d > $W/Dep/SrsTarget/svl/res.d [ build LNK ] Library/fsstorage.uno.so R=/build/src && S=$R/build && O=$S/solver/340/unxlngx6.pro && W=$O/workdir && mkdir -p $W/SrsTarget/svl/ && cat $W/SrsPartTarget/svl/source/misc/mediatyp.src $W/SrsPartTarget/svl/source/items/cstitem.src > $W/SrsTarget/svl/res.srs /bin/sh: line 1: 10897 Segmentation fault make -r -j10 dmake: Error code 139, while making 'all' This can be reproduced. I can't remember any other project in our repositories failing that often with latest gcc/binutils. -Andy PS: Using bison 2.5 also breaks the build: In file included from /build/src/build/connectivity/source/parse/wrap_sqlbison.cxx:32:0: ../../unxlngx6.pro/misc/sqlbison.cxx: In function 'int SQLyyparse()': ../../unxlngx6.pro/misc/sqlbison.cxx:7814:9: error: invalid conversion from 'const char*' to 'sal_Char*' [-fpermissive] ../../inc/connectivity/sqlparse.hxx:235:14: error: initializing argument 1 of 'void connectivity::OSQLParser::error(sal_Char*)' [-fpermissive] CXXFLAGS may need a fix here. Should I file a bug for this?
