[Bug debug/14114] New: ICE in gen_subprogram_die

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

gcc crashes compiling the C code below, if both debugging and optimization
are on:

$ ./cc1 x.c -quiet -g -O2
x.c: In function `a':
x.c:5: internal compiler error: in gen_subprogram_die, at dwarf2out.c:10696
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

It's tripping over this abort in gen_subprogram_die:

	  /* ??? This can happen if there is a bug in the program, for
	     instance, if it has duplicate function definitions.  Ideally,
	     we should detect this case and ignore it.  For now, if we have
	     already reported an error, any error at all, then assume that
	     we got here because of an input error, not a dwarf2 bug.  */
	  if (errorcount)
	    return;
	  abort ();

Environment:
System: Linux karma 2.6.1 #10 Tue Feb 10 04:31:35 EST 2004 i686 i686 i386 GNU/Linux
Architecture: i686

	<machine, os, target, libraries (multiple lines)>
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc/configure --prefix=/usr/local/gcc --enable-threads=posix --enable-long-long --enable-languages=c,c++,f77

How-To-Repeat:

Compile with -g -O2:

---------------------------------------
void a()
{
  void c();
  c();
}

void b()
{
  void c();
}

void c() {}
