           Summary: ICE in gen_subprogram_die for nested function
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: debug
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: rsandifo at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org,rsandifo at gcc dot gnu
                    dot org
GCC target triplet: i686-pc-linux-gnu

Sorry if this already a known problem!  I tried searching for it but
couldn't find anything.

The following test case:

int f1 (int y)
{
  int f2() { return y; }
  return f2();
}

causes an ICE on i686-pc-linux-gnu if compiled with -O2 -g:

/tmp/foo.c: In function `f2':

/tmp/foo.c:5: internal compiler error: in gen_subprogram_die, at dwarf2out.c:10614
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

It works OK if compiled with -O3 -g or with -O2 -fno-unit-at-a-time -g.

At a guess, I think that dwarf code is getting confused by the inlining
of functions that aren't marked !DECL_INLINE.  It'll be a few days
before I can look into much more though.
