fsf cvs gdb says: unable to read unknown load command 0x1a
and crashes afterwards.

This happens for code as simple as

-----------------------------------
//#include <QtCore/QCoreApplication>

int main(int argc, char *argv[])
{
//    QCoreApplication a(argc, argv);
//    QString name(argv[0]);

    return 0;
}
-----------------------------------

[I.e. basically a 'return 0;']

for a binary build with 

g++ -c -pipe -g -gdwarf-2 -arch x86_64 -Xarch_x86_64 -mmacosx-version-min=10.5
-Wall -W -DQT_CORE_LIB -DQT_SHARED -I../../../git/qt/qt-4.6/mkspecs/macx-g++
-I../../qt-test-app
-I../../../git/qt/qt-4.6/lib/QtCore.framework/Versions/4/Headers
-I../../../git/qt/qt-4.6/include/QtCore -I../../../git/qt/qt-4.6/include -I.
-I../../qt-test-app -I. -F/data/git/qt/qt-4.6/lib -o main.o
../../qt-test-app/main.cpp

g++ -headerpad_max_install_names -arch x86_64 -Xarch_x86_64
-mmacosx-version-min=10.5 -o qt-test-app main.o -F/data/git/qt/qt-4.6/lib
-L/data/git/qt/qt-4.6/lib -framework QtCore -L/data/git/qt/qt-4.6/lib

That's a plain Qt based application using a default 4.6 install of Qt.

[The qmake file generating that line is:

-----------------------------------
QT       += core
QT       -= gui

TARGET = qt-test-app
CONFIG   += console
CONFIG   -= app_bundle

SOURCES += main.cpp
-----------------------------------
