             Bug #: 13722
           Summary: lookup_global_symbol does not seem to work
           Product: gdb
           Version: 7.4
            Status: NEW
          Severity: normal
          Priority: P2
         Component: python
        AssignedTo: unassigned@sourceware.org
        ReportedBy: gabenbecca@gmail.com
    Classification: Unclassified


When a corefile is generated and I attempt post-mortem debugging:

e.g. gdb ./foo foo.core.15180

info address works (e.g.):
(gdb) info address main

Symbol "main" is at 0x4145f0 in a file compiled without debugging.

but python api searching for the same symbol does not work:


(gdb) python print gdb.lookup_global_symbol("main")
None

other variations where I pass in different domains yeild the same results 

(gdb) gdb.lookup_global_symbol("main",gdb.gdb.SYMBOL_FUNCTIONS_DOMAIN)
None

Not sure what information I can provide?
