+++ This bug was initially created as a clone of Bug #441406 +++ Description of problem: On repeated PTRACE_SINGLESTEP when a signal gets delivered the signal handler gets traced but on the `int 0x80' of `__kernel_sigreturn' it starts to PTRACE_CONT instead. Version-Release number of selected component (if applicable): FAILs kernel-2.6.25.4-30.fc9.i686 How reproducible: Always. Steps to Reproduce: wget -O step-through-sigret.c 'http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/tests/ptrace-tests/tests/step-through-sigret.c?cvsroot=systemtap'; gcc -o step-through-sigret step-through-sigret.c -Wall -ggdb2 -D_GNU_SOURCE; ./step-through-sigret; echo $? Actual results: 1 Expected results: 0
Thanks, verified as fixed on kernel-2.6.25.9-76.fc9.x86_64.
