1. Open project simple.pro from Creator's sources.
2. In file simple_gdbtest_plugin.cpp, add a comment above the definition of function pluginTest().
3. Add a breakpoint in the line of this comment.
4. Build the project with MinGW.
5. Run the project in gdb.
   Execution will stop at the first line of actual code below the breakpoint. The breakpoint icon will jump to this line for an instant and then right back to the comment. In the other file of the project, it works correctly.

This is a regression. It works in 2.1.0.
