In certain cases, we call functions on a completely separate stack from the one that the thread normally uses. In these cases, GDB fails to do a backtrace through the function call with an UNWIND_INNER_ID error, even though all the correct stack unwinding debug information is present. Is it acceptable to make a patch that allows this check to be turned off (i.e. "set frame-inner-check off" or similar), or is there another method that is more acceptable? -- Joshua Watt
