cppcheck analysis of qt-x11-free_3.3.8b-7.dsc

• ./examples/demo/opengl/glinfo_x11.cpp:196 [error] - instance of "visualAttribs" object destroyed immediately
• ./src/kernel/qjpegio.cpp:82 [error] - Uninitialized variable: buffer
• ./src/kernel/qmngio.cpp:192 [error] - Common realloc mistake: "buffer" nulled but not freed upon failure
• ./qmake/generators/mac/metrowerks_xml.cpp:751 [style] - The iterator incrementing is suspicious - it is incremented at line 751 and then at line 725 The loop might unintentionally skip an element in the container. There is no comparison between these increments to prevent that the iterator is incremented beyond the end.
• ./qmake/generators/makefile.cpp:107 [error] - Common realloc mistake: "big_buffer" nulled but not freed upon failure
• ./qmake/generators/makefile.cpp:125 [error] - Resource leak: file
• ./qmake/generators/unix/unixmake.cpp:421 [style] - The iterator incrementing is suspicious - it is incremented at line 421 and then at line 413 The loop might unintentionally skip an element in the container. There is no comparison between these increments to prevent that the iterator is incremented beyond the end.
• ./qmake/generators/unix/unixmake.cpp:688 [style] - The iterator incrementing is suspicious - it is incremented at line 688 and then at line 653 The loop might unintentionally skip an element in the container. There is no comparison between these increments to prevent that the iterator is incremented beyond the end.
