+++ This bug was initially created as a clone of Bug #284311 +++

Description of problem:
For the user-level impact see the Bug 284311.

If one signals the inferior during PTRACE_CONT and the inferior's handler is
using SA_RESETHAND then the signal will be delivered to the default handler (the
 installed one gets ignored).

Version-Release number of selected component (if applicable):
kernel-2.6.18-48.el5.x86_64

Steps to Reproduce:
1. gcc -o sa-resethand-on-cont-signal sa-resethand-on-cont-signal.c -Wall -ggdb2

Actual results:
FAIL

Expected results:
PASS
