           Summary: Template class definition generates error
           Product: gcc
           Version: 2.96 (redhat)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++

        ReportedBy: menita dot singh at schwab dot com
                CC: gcc-bugs at gcc dot gnu dot org

I get a compile error "Internal Error: Segmentation Fault", at this line, where 
i define:

template<class ValueType> class ArrayListImpl<ValueType>::Itr : public 
Iterator<ValueType> {

}
Previoulsy i define:
template<class ValueType> class ArrayListImpl : public List<ValueType>::Impl{
private class Impl;
.....[other stuff]
}

Read <http://gcc.gnu.org/bugs.html>, we do not want just a snip of your code.

That's not what Andrew meant. We need a complete testcase which we can try 
to compile. Leaving out stuff with "//...more stuff" is not sufficient. Please read the 
page Andrew pointed you to to see what kind of information we need (read the 
section on preprocessed sources). 
 
Thanks

You still are not getting the point the code you gave will not work on any compiler as where is List 
defined and other classes.
>From http://gcc.gnu.org/bugs:
What we need (all of these are needed)
Please include in your bug report all of the following items, the first three of which can be obtained 
from the output of gcc -v:
the exact version of GCC;
the system type;
the options given when GCC was configured/built;
the complete command line that triggers the bug;
the compiler output (error messages, warnings, etc.); and
the preprocessed file (*.i*) that triggers the   bug, generated by adding -save-temps to the 
complete   compilation command, or, in the case of a bug report for the GNAT front end,   a 
complete set of source files (see below).

What we do not want:(this is what you gave us so far.)
A code snippet that won't cause the compiler to produce the   exact output mentioned in the bug 
report (e.g., a snippet with just   a few lines around the one that apparently triggers the bug,   with 
some pieces replaced with ellipses or comments for extra   obfuscation :-)
Bugs in releases or snapshots of GCC not issued by the GNU   Project.  Report them to whoever 
provided you with the release

2.96 is a non-supported version, also there has been many releases since 2000. 3.3.1 is 
the lastest, 3.3.2 will be released next month.
Closing as there is no way to reproduce this without a testcase but I would try a newer 
GCC first any way.
