Synopsis: GCC 2.95.3-5 prints internal error.

State-Changed-From-To: open->analyzed
State-Changed-By: rodrigc
State-Changed-When: Fri Apr 12 18:20:13 2002
State-Changed-Why:
    Compiling with gcc 3.1 results in the following compiler
    error:
    
    main.cpp: In instantiation of `TableMap<int>':
    main.cpp:18:   instantiated from here
    main.cpp:6: Internal compiler error in tree_low_cst, at tree.c:3471
    Please submit a full bug report,
    with preprocessed source if appropriate.
    See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
    
    
    If I compile with:
    g++ -Wall -pedantic-errors main.cpp
    
    I get:
    
    main.cpp: In instantiation of `TableMap<int>':
    main.cpp:18:   instantiated from here
    main.cpp:9: ISO C++ forbids variable-size array
    main.cpp:6: confused by earlier errors, bailing out
    
    
    You can work around this problem by changing:
    
    int items[Index_max+1];
    
    to:
    
    int items[Index_max];
    
    
    This is a problem in gcc that should be fixed.
