Hi,

Here are collected some of the problems we have with some of the latest
versions of egcs.
The code that generated the errors, the bug report itself and the
generated files (ii and s) are archived at:

http://borco-ei.eng.hokudai.ac.jp/~borco/bugs/template.tar.gz

The archive is arround 500 kB so I make it available on http as you've
requested.

I attache the bug_report file, pressent also in the above archive.

My computer is a Pentium II machine running Debian Potato (glibc 2.1,
kernel 2.2.5).

TIA,

Ionutz

Bug Report for templates in EGCS
================================

All the problematic code was reported to compile with:

egcs-2.90.29 980515 (egcs-1.0.3 release)
M$ Visual C++ 5.0/6.0 on win95/98/NT
Borland C++ v. 5.0c on win95/98/NT
g++ 2.8.0 on solaris 2.6

It seems that newest egcs have problems with templates, 
especially subclassing templates classes.
Another problem is with void* NULL conversion related 
to ANSI C++ restriction.

The code that generated these errors, this report  and 
the generated files can be found at:
