            Bug ID: 16880
           Summary: GDB does not step into template functions OS X
                    Mavericks
           Product: gdb
           Version: 7.7
            Status: NEW
          Severity: normal
          Priority: P2
         Component: breakpoints
          Assignee: unassigned at sourceware dot org
          Reporter: vsoftco at gmail dot com

Hi,

I am using gdb on OS X Mavericks, and whenever I try to step in a template
function, gdb steps over (same when I set a breakpoint inside a template
function, it is never reached, as if the breakpoint does not exist). This
happens for even the simplest template functions defined inside of main.cpp. My
target OS is OS X Mavericks, I used both gdb 7.6 and gdb 7.7, same behaviour. I
tried it on more than one machine that runs Mavericks.

I also tried using various versions of g++ (4.7, 4.8, 4.9) to compile my
program. I also tried to use -fno-inline option when compiling, still same
thing...

Under any other OS (Linux/Windows/Solaris), gdb steps in template functions. It
seems to be a problem related to OS X Mavericks.

Thanks!

Created attachment 7565
  --> https://sourceware.org/bugzilla/attachment.cgi?id=7565&action=edit
simple main.cpp file with template function in line 16

When trying to step into template function f<int>(12) on line 16, gdb just
steps over. If f is non-templated, everything works as it is supposed to, i.e.
steps into f. Target OS: OS X Mavericks, g++-(4.7,4.8,4.9) gdb-(7.6,7.7)

I have also compiled gdb from source (instead of using the macports version),
again no ability of stepping in template functions.

If I compile the program with g++ -fno-weak flag, then GDB steps inside
templated functions. However, -fno-weak seems to be a deprecated flag, used by
g++ to force non-weak symbol tables.
