Description Dan Morrill 2003-04-07 22:04:41 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021212

Description of problem:
gcc -v:
Thread model: posix
gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)

I will attach input files:  framework.c, framework.h, area.h, framework.cpp.  I
do not have a more reduced test case.

Error is this:
g++  -g -Wall  -c -o framework.o framework.cpp
framework.cpp:23: Internal compiler error in splice_child_die, at dwarf2out.c:
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:> for instructions.

See attached source files.  Should be fairly self-explanatory, but let me know
if it's not.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
See code.

Additional info:

Mere formality, but... source code is not a trivial test case, but it's
BSD-licensed, so it's okay to throw around as needed.

Comment 5 Dan Morrill 2003-04-07 22:11:35 UTC
I have attached the problematic files -- I think this should compile but I am
not sure since gcc dies out. :)

If I can work around it I will add that info to this entry.

Comment 6 Dan Morrill 2003-04-07 22:18:07 UTC
Apparent workaround:  due to a copy-and-paste issue from area.h (the parent
class) there are a number of methods in framework.h that are defined to be
abstract but for which bodies exist in framework.cpp.  So, this is a
syntactically incorrect C++ file.

Obviously, that wasn't a graceful failure mode, though.

I will attempt to reproduce with a simpler test case...

Comment 7 Richard Henderson 2004-10-03 19:42:00 UTC
Actually, function bodies for abstract virtual functions is just fine.
You aren't allowed to invoke them implicitly (this->foo()), but you are
allowed to invoke them explicitly (this->base::foo()).

The real problem is that Framework::getName is implemented twice.  If
you remove the -g flag, the compiler won't crash, but you'll get 

/tmp/ccJPpA05.s: Assembler messages:
/tmp/ccJPpA05.s:505: Error: symbol `_ZN9Framework7getNameEv' is
already defined

Current versions of the compiler don't crash in the debug info, but
they don't diagnose the duplicate function definition either. Pushed
upstream to
