             Bug #: 13544
           Summary: Error while converting hex to object pointer: "A
                    syntax error in expression, near"
           Product: gdb
           Version: 7.3
            Status: NEW
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@sourceware.org
        ReportedBy: yuri@tsoft.com
    Classification: Unclassified


I have the class XObject defined globally and application is built with the
debug info.
However, attempting to cast some hex value to the pointer to this class gives
me an error:

(gdb) p (XObject*)0x848cdd420
A syntax error in expression, near `)0x848cdd420'.

For some weird reason, casting to some subclass of XObject works fine.

gdb-7.3.1 on FreeBSD-8.2 (build from the source)
but this error was observed on several previous versions as well.

Same happens when 0x848cdd420 is replaced with just 0.

I would also like to point out that this error doesn't mean that the class
isn't known, in case of unknown class the error says this explicitly:

(gdb) p (XObject1*)0
No symbol "XObject1" in current context.

A test case would be helpful.

My attempt at a simple test case didn't show the problem.

I am going to guess this is a dup of PR 8888.
