[Bug middle-end/20521] New: ICE in cgraph.C with C++

[bredelin at ucla dot edu]

While compiling a source file, I get the following error:

smodel.C:1164:1: internal compiler error: in cgraph_mark_reachable_node, at
cgraph.c:475

This is with today's (Mar 17, 2005) CVS, with Richard's Guenther's patch to
modify inlining heuristics.  These options trigger the ICE:

% g++-cvs -O smodel.ii -c

This testcase is preprocessed source from the file that causes the ICE.

Here is the testcase.

which one? please add references to all patches you installed or, better, try to
reproduce ICE with clean tree by adding appropriate --param options.

1. For now, I will just include the patch:

diff -r1.170 tree-inline.c
1249a1250
 >     case TARGET_EXPR:
1250a1252,1253
 >       if (DECL_P (x) && DECL_IGNORED_P (x))
 >       break;
1252d1254
<     case TARGET_EXPR:

2. However, it seems that as of Mar 18 CVS, the crash no longer occurs.
This is probably because of this change:

Fri Mar 18 10:00:16 2005 UTC  by hubicka
	PR middle-end/20225
	* cgraph.c (cgraph_mark_reachable_node): Assert that it is not called
	too late.
	* varasm.c (find_decl_and_mark_needed): Mark needed only when not
	called too late.

3. This patch might be reversed:

http://gcc.gnu.org/ml/gcc-patches/2005-03/msg01869.html

If the regression returns, I will try to find --param options that cause 
the ICE on a clean tree.
