In lazarus /debugger/test/Gdbmi is a program TestGdbmi

If I insert a breakpoint at line 480 (either before start, or during run, then GDB reports :

> TCmdLineDebugger.SendCmdLn "-exec-continue"

<< TCmdLineDebugger.ReadLn "^error,msg="Warning:\nCannot insert breakpoint 9.\nError accessing memory address 0x18: Input/output error.\n" "
TGDBMIDebugger.ProcessResult Error: ,msg="Warning:\nCannot insert breakpoint 9.\nError accessing memory address 0x18: Input/output error.\ n"
<< TCmdLineDebugger.ReadLn "(gdb) "

Can anyone try if they get the same?

Oh, and the problem goes away, if I use the external linker -Xe
