After a recent change to runtime-gdb_test.go the ppc64le builder has had intermittent failures. The failures occur when trying to invoke the goroutineCmd function to display the backtrace for a selected goroutine. There is nothing wrong with the testcase but it seems to intermittently leave goroutines in a state where an error can occur. The error message indicates that the problem occurs when trying to change the sp back to the original after displaying the stacktrace for the goroutine. gdb.error: Attempt to assign to an unmodifiable value. After some searching I found that this error message can happen if the sp register is changed when on a frame that is not the top-most frame. To fix the problem, frame 0 is selected before changing the value of sp. This fixes the problem in my reproducer environment, and hopefully will fix the problem on the builder.
