P.S. GO OUT AND VOTE Build me a brick wall! What do you call a relay that self-opens on power loss? This is what Joachim and BLUEPIXY are getting at. his comment is here
So I compiled the sample program ( https://github.com/slaff/Sming/blob/feature/gdb-dev/Basic_Debug/app/application.cpp ) that turns the led on and off. As @Joachim Pileborg & @BLUEPIXY point out, the for() loops are executing once too often. It a simple stack based buffer overflow exploit. So, that being the only difference, I changed it and it worked.
But the instruction pointer is on the stack, it's not covered by any debug info. This stub is made to work with the open-source xtensa-lx106-elf-gdb as built by e.g. Reload to refresh your session. Gdb Assembly View Not the answer you're looking for?

I can debug fine on either system alone but only have this issue when using "remote" to debug one from the other. Possible outcomes of fight between coworkers outside the office How were Lisps usually implemented on architectures that has no stack or very small stacks? When debugged locally it does break of course.
Type "layout asm", "start" instead. Gdb Show Registers The "info source" command states that my test.cpp source is loaded but the debugger appears not to know where it has stopped. The code generated by the compiler may include safeguards against accepting the buffer overflow itself. I suspect it's shared libraries not matching but I'm unsure about that and was hoping maybe someone had seen this before.

I guess I just assumed because gdb didn't have source code that step would revert to assembly instructions. –Paul Mar 11 '10 at 3:31 note: you often can't type Gdb Assembly Debugging After debugging with gdb I found the address of the shell code as it will pass as a parameter, and right after the strcpy I examine the stack and the $ebp+8 Code: [Select]C:\lazarus\lazarus.exe --debug-log=C:\mylazlog.txt --debug-enable=DBG_CMD_ECHO,DBG_STATE,DBG_DATA_MONITORS,DBGMI_QUEUE_DEBUG,DBGMI_TYPE_INFO
