[Bug c++/16980] New: internal compiler error: in cp_expr_size, at cp/cp-lang.c:330

[yanliu at ca dot ibm dot com]

This is a regression from g++3.3. With g++3.3, the testcase passed, but with g++
3.5, it failed with internal compiler error:
t.C:11: warning: direct base `c4' inaccessible in `c15' due to ambiguity
t.C:19: warning: `v3' initialized and declared `extern'
t.C: In function `void __static_initialization_and_destruction_0(int,
int)':internal compiler error: in cp_expr_size, at cp/cp-lang.c:330. 

I am using g++ 3.5 version on powerpc apple MacOS system. Using gcc3.3, I am
getting this message without compiler abend.
t.C:11: warning: direct base `c4' inaccessible in `c15' due to ambiguity
t.C:19: warning: `v3' initialized and declared `extern'

Already fixed in later versions of 3.5.0.

Hi Yan, 
how nice to meet you on this forum as well :-) 
 
In any case, it is indeed fixed, and also works on the 3.4 branch with a 
checkout from yesterday. The messages I get are the same that you show 
for 3.3.

I should note that "gcc version 3.5.0-tree-ssa 20040321 (merged 20040529) (Apple Computer, Inc. 
build 1768)" is not the latest Apple 3.5.0 gcc, but gcc 3.5.0 build 1771 is, you can check it out on the 
FSF cvs with the tag apple-gcc-1771.
