GDB 5.1
>Description:
Debugging information seems totally broken.
When I compile a trivial C or C++ program, GDB tells me :

Dwarf Error: Cannot handle DW_FORM_strp in DWARF reader.

I can't even put a breakpoint on "main".

This shows up with current GCC 3.1 and 3.2 (gcc and g++).
2.95.3 and 3.0.4 both work fine.
This seems critical for the 3.1 release !
>How-To-Repeat:
Compile with "-g", with gcc or g++ the following program:
int main() { return 0; }

Then run "gdb a.out", and then type "b main" in gdb.
>Fix:
I don't know of any fix.

    Not a GCC bug.
    You simply need to upgrade your GDB.
    Latest GDB CVS supports this.
    5.1.1 supports it as well, IIRC.

 Update gdb to the cvs version, or when gdb 5.1.1 comes out that.
 Since gdb 5.1 does not support all of the dwarf 2 debugging stuff.
 
 Thanks,

 Easy, use GDB 5.1.1.  Released for (among others) this exact reason.  I
 do wish we had not switched to a DWARF-2 default at the same time as
 this...
