Use of atexit for destructors on Solaris 7.

[Charles Galambos <c dot galambos at eim dot surrey dot ac dot uk>]

Hi,

I've just encountered a problem with the implementation
of destructors on Solaris 7.    It seems the use the
'atexit' function, this function registers at most 34
functions under solaris 7.

Compiler version:

% g++ -v
Reading specs from /opt/GNUdevelop/gcc-2.95.2/lib/gcc-lib/sparc-sun-solaris2.7/
2.95.2/specs
gcc version 2.95.2 19991024 (release)


I've written a short program to show the problem. The program outputs 
the following an 'x' for each constructor and a 'y' for each destructor.
The programs outputs the followin:

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy


Showing not all the destructors where called.  I've had a hunt
around the faq's and egcs-bugs archive and haven't found
any work arounds mentioned.
