I want to check object code with two versions of libQtCore.a

Qt Enthusiast

am also making static library of Qt (qt.4.3.3) , the steps to do the same are

I downloaded a open source of qt-all-opensource-src-4.3.3. I built static libraries using following steps. The gcc version I am using is gcc 5.2.0

cd qt-all-opensource-src-4.3.3
gmake conflcean
./configure -release -static -largefile -qt3support -qt-libpng -qt-libmng -qt-libtiff -qt-libjpeg -glib -platform linux-g++-64 -confirm-license -no-openssl -no-qdbus -prefix ./static_new -prefix-install -opengl -sm -lSM -lICE -xshape -lX11 -xinerama -lXinerama -xcursor -lXcursor -xfixes -lXfixes -xrandr -lXrandr -xrender -lXrender -fontconfig -lfontconfig -tablet -lXi -xkb -glib -lglib-2.0 -lXext -lz -lgthread-2.0
gmake
gmake install
I am getting following error message

from ../../corelib/codecs/qsimplecodec_p.h:36, from ../../corelib/codecs/qsimplecodec.cpp:22: ../../../include/QtCore/../../src/corelib/thread/qatomic.h: In instantiation of ?QAtomicPointer::QAtomicPointer(T*) [with T = QByteArray]?: ../../corelib/codecs/qsimplecodec.cpp:592:74: required from here

I did two experiments

Experiment1 : compiled the Qt4.3.3 with -fpermissive flag and I got version of libQtCore.a and got succesfull build
Experiment2 : corrected the code and used this-init insted of init at line 190 and build passed
Now I have to compare the object code generated with two versions of libQtCore (from two experiments) . I tried to use following command and got successful build
objdump -t /pathtoQt/experiment1/libQtCore.a | grep -i atomic
objdump -t /pathtoQt/experiment2/libQtCore.a | grep -i atomic
but I am not get any reference of QAtomicPointer in the objdumps .

Can someone guide me how to compare the object code generated with the -fpermissive flag against the corrected code that uses { this->init(t); } in the line that causes the error.
