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. How reproducible: always. Steps to Reproduce: 1. g++ test1.cpp Actual results: % g++ test1.cpp g++: Internal error: Segmentation fault (program cc1plus) Please submit a full bug report. See <URL:http://bugzilla.redhat.com/bugzilla> for instructions. Expected results: I'm not sure -- I may be violating something in the c++ spec, but I didn't expect to get the internal error. Additional info: 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.
