             Bug #: 13796
           Summary: disp-step-syscall.exp: vfork
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: server
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jan.kratochvil@redhat.com
    Classification: Unclassified


After fixing gdb.base/disp-step-syscall.exp to properly test what it tests it
has revealed:

stepi
Program terminated with signal SIGILL, Illegal instruction.
The program no longer exists.
(gdb) PASS: gdb.base/disp-step-syscall.exp: vfork: single step over vfork
Child terminated with signal = 0x4 (SIGILL)
GDBserver exiting
print /x $pc
No registers.
(gdb) FAIL: gdb.base/disp-step-syscall.exp: vfork: get hexadecimal valueof
"$pc" (timeout)

It works with linux-nat so it seems like a gdbserver (and not kernel) issue.
