I suggest: You need to enable the debugger plugin debug log, and post the log here or on the forum.

Hm, for some reason the debugger is inserting two breakpoints.
Can you try newer version of gdb, 6.8 is quite old already...

Dear tpetrov : I have change GDB to V7.4 , but is occur other problem , when I add two breakpoints at the same time (breakpoint in line 295,314), break in line 295,314 after remove them , but Codeblocks only remove a breakpoint (295) , the 314 breakpoint cannot removed , please see below debug info , thanks .

I see no "delete breakpoint 4" command and so no one has deleted the breakpoint.
Can you open the "Breakpoints" dialog and tell me what is the index of the breakpoint just before you delete it? I guess it will be -1 and for some reason you log is pretty garbled and the commands and their results are interleaved, which messes up the debugger.
Can you reproduce this with non embedded debugger and executable?
titanping 2012-05-09 02:58
Dear tpetrov :
I have open "Breakpoints" dialog see the breakpoint 'index' value , It really is -1 , so can't delete it , Can you tell me how to solve this problem? Thanks !
ptdev 2012-05-28 09:50
Can confirm that the same thing happens under Windows: once a breakpoint has been added, removing it only happens in the UI: GDB keeps breaking in the same place.
The only workaround for this is to restart the debugging session.
