             Bug #: 13944
           Summary: ftell: text variable, no debug info
           Product: glibc
           Version: 2.14
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
        AssignedTo: unassigned@sourceware.org
        ReportedBy: giecrilj@stegny.2a.pl
                CC: carlos@systemhalted.org
    Classification: Unclassified


Steps to reproduce:

{ gdb true; }
run
p ftell
ptype ftell

Actual result:

{<text variable, no debug info>} 0x7ffff7ab3ce0 <_IO_ftell>
int ()

Expected result:

{long (FILE *)} 0x7ffff7ab3ce0 <_IO_ftell>
long (FILE *)

This bug confuses gdb a lot; if you have a file pointer f positioned at
0x400000000, gdb will print 0 for ftell (f).

Workaround: p _IO_ftell (f).

Could you please follow:
http://www.gnu.org/software/libc/bugs.html

Are you using your own glibc or one from your distribution?

Can you reproduce with a glibc built from trunk?

I think this is a gdb bug.  It should handle aliases by looking up the real
symbol.
