clang output with crash report
I keep running into crashes when trying to build Qt Creator with LLVM from
trunk. Clang 3.7 builds the code just fine and so did trunk two weeks ago.
This is the actual command being run:
clang++ -c -pipe -Qunused-arguments -g -fvisibility=hidden
-fvisibility-inlines-hidden -std=gnu++11 -Wall -W -D_REENTRANT -fPIC
-DWITH_TESTS -DIDE_LIBRARY_BASENAME=\"lib\" -DQT_CREATOR -DQT_NO_CAST_TO_ASCII
-DQT_NO_CAST_FROM_ASCII -DQT_USE_FAST_OPERATOR_PLUS -DQT_USE_FAST_CONCATENATION
-DQTC_CPU=X86Architecture -DPROJECTEXPLORER_LIBRARY -DQT_PLUGIN -DQT_QUICK_LIB
-DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_QML_LIB -DQT_NETWORK_LIB -DQT_TESTLIB_LIB
-DQT_CONCURRENT_LIB -DQT_CORE_LIB
-DQT_TESTCASE_BUILDDIR='"/home/code/build/creator-clang-no-asan/qtcreator/src/plugins/projectexplorer"'
-I../../../src -I/home/code/src/creator/qtcreator/src/libs
-I/home/code/src/creator/qtcreator/tools
-I/home/code/src/creator/licensechecker/plugins
-I/home/code/src/creator/perfprofiler/plugins
-I/home/code/src/creator/qtcreator/src/plugins -I.
-I/home/code/src/qt5-dev-build/qtbase/include
-I/home/code/src/qt5-dev-build/qtbase/include/QtQuick
-I/home/code/src/qt5-dev-build/qtbase/include/QtWidgets

.obj/debug-shared/customwizard.o
/home/code/src/creator/qtcreator/src/plugins/projectexplorer/customwizard/customwizard.cpp
and that reliably crashes for me. "crash.E" was created using:
clang++ -E -pipe -Qunused-arguments -g -fvisibility=hidden
-fvisibility-inlines-hidden -std=gnu++11 -Wall -W -D_REENTRANT -fPIC

-I/home/code/src/qt5-dev/qtbase/mkspecs/linux-clang -o /tmp/crash.E
/home/code/src/creator/qtcreator/src/plugins/projectexplorer/customwizard/customwizard.cpp
Building crash.E using:
clang++ -c -pipe -Qunused-arguments -g -fvisibility=hidden
-fvisibility-inlines-hidden -std=gnu++11 -Wall -W -fPIC -o /tmp/crash.o
/tmp/crash.E
does *NOT* crash.
So I am a bit lost as to how to reproduce this:-/
