Ok, the bug with the overlaps disappeared with a more recent trunk version.
GDB 7.4.1 says that: (gdb) s Single stepping until exit from function _Workspace_Handler_initialization, which has no line number information. 0x00000410 in bsp_work_area_initialize () Other debugger refuse to load the ELF file. Has someone a hint how I can check that the debug information is ok?
This was due to the new DWARF 4 debug information emitted by GCC 4.8. GDB 7.5 can cope with it.
