Description Andrew Cagney 2006-11-22 17:25:17 UTC

Should end up somewhere in the signal handler, typically at the first
instruction.

Watch for kernel bugs, can instead let the process exit.

Comment 1 Mark Wielaard 2007-02-13 13:35:14 UTC

There are now a couple of tests that handle signal delivery while stepping and
the TaskState machinery has been expanded to handle it (see
LinuxPtraceTaskState.Running.handleTrapEvent()). Kernel bugs have been found,
sigh (see bug #3997). A test could be added to make sure that we land on the
first instruction of the signal handler.
