Red Hat Bugzilla – Bug 142090
If an array of structs in a base class is too large, derived class will not compile.
Last modified: 2007-11-30 17:10:56 EST
Description of problem:
When a base class has an array of structs as a public member, and this
struct has an array of strings as a member, compiling a derived class
results in an internal error if the sizes of the arrays are too large.
Version-Release number of selected component (if applicable):
% g++ --version
g++ (GCC) 3.3.3 20040412 (Red Hat Linux 3.3.3-7)
Copyright (C) 2003 Free Software Foundation, Inc.
Steps to Reproduce:
1. g++ test1.cpp
% g++ test1.cpp
g++: Internal error: Segmentation fault (program cc1plus)

I'm not sure -- I may be violating something in the c++ spec, but I
didn't expect to get the internal error.
If you change the number of sections to 50, the code compiles fine.
Also, if you change the size of the struct member array called
'variable' to 1000, the program compiles fine. I did not try to
figure out the exact sizes for which the program starts to fail.
Also interesting is if you get rid of the derived class, you can make
the sizes even larger in the base class and it will compile fine.
