Though this bug has been declared invalid, I experience something similar with a much simpler example, shown under the double line of "=" symbols.
When main.cpp is compiled manually using g++ main.cpp -o VideoShow -I/usr/include/opencv -lcv -lcvaux -lcxcore -lhighgui all works fine... However, when exactly the same code is compiled using src.pro to generate the Makefile using qmake, the program crashes creating the following backtrace (attached backtrace.gif, also available at http://telin.ugent.be/~frooms/backtrace.gif) Anyone an idea? Any suggestions or help is greatly appreciated.
