Revision 09636efd1bd164ac782ff0d3a714db2c53964776 authored by David Matlack on 22 September 2022, 23:17:23 UTC, committed by Paolo Bonzini on 30 September 2022, 10:38:00 UTC
Bail out of test_dump_stack() if the stack trace is empty rather than invoking addr2line with zero addresses. The problem with the latter is that addr2line will block waiting for addresses to be passed in via stdin, e.g. if running a selftest from an interactive terminal. Opportunistically fix up the comment that mentions skipping 3 frames since only 2 are skipped in the code.
