Some bug

[Maciej Hrebien]

Hi!

OS: RedHat Linux 6.0 with kernel: 2.2.5-15
egcs, egcs-c++ and cpp with version 1.1.2-12
And I use KDE.

I was learning exception handling and I wrote some example programm with
a little mistake. When I was compilling it my disk was working hard and
then the system stopped. After restart I found the mistake, recompiled 
the program and all was OK. The programm is attached to this mail.

// The mistake is in template class pointer.

Before my system stopped I sow the compiler message:
In instantiation of 'pointer<int>':
instantiated from here
invalid use of undefined type 'class pointer<int>'
and that was in line 65.


So, that's all.
I look forward to hearing from You.
