Hello! There are two stacks in the program: one is created by OS and the second is created by program itself to run some code with it.

When the program crashes in the second stack, I want to switch to the main stack in gdb and see the backtrace. Is it possible?

I tried to save the rsp to a variable and change it after the crash, but the resulting backtrace was not right. I think gdb cannot differentiate frames in stack.
