[Bug python/14391] New: gdb.Breakpoint.stop callinggdb.parse_and_eval("(int) $rax") + Ctrl^C crashes GDB (assertion fail)


http://sourceware.org/bugzilla/show_bug.cgi?id=14391

             Bug #: 14391
           Summary: gdb.Breakpoint.stop calling gdb.parse_and_eval("(int)
                    $rax") + Ctrl^C crashes GDB (assertion fail)
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: normal
          Priority: P2
         Component: python
        AssignedTo: unassigned@sourceware.org
        ReportedBy: kevin.pouget@gmail.com
    Classification: Unclassified

Backtrace of the failing assertion

In gdb.Breakpoint.stop callback, the script reads a register value with
gdb.parse_and_eval("(int) $rax"). The callback always returns False, so GDB
never actually gives the control back to the CLI.

Sometimes (certainly a matter of timing), when I hit Ctrl^C, GDB crashes (a
failing assertion) with the backtrace in the attachment.

There is no other problem with the script.
