[Bug 328299] [NEW] testcase.cpp: internal compiler error: Segmentation fault.

[dazjorz]

Public bug reported:

I'm using qt4-x11 version 4.4.3-0ubuntu1.2 from intrepid-proposed. I was
trying to compile KMess when I noticed an internal compiler error on
using QMaps. I read in the gcc FAQ that these are usually because of
errors in any of the code it is trying to compile or link, therefore I
am reporting here. Please tell me if I should bugreport against gcc
instead.

I wrote a test case which I have attached. The gcc-testcase.pro file was
simply generated by qmake -project. Compiling this project gives the
following output:

$ make
g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtGui -I/usr/include/qt4 -I. -I. -I. -o testcase.o testcase.cpp

testcase.cpp:6: warning: unused parameter 'argv'
testcase.cpp: In member function 'bool QBasicAtomicInt::operator!=(int) const':
testcase.cpp:18: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.3/README.Bugs> for instructions.
