Hi folks.... thought I'd bother you all with a problem I've been having
for some time.

I have a C++ program, which #includes my own Array and Matrix template
classes.  These work by using one pointer which points to the top of the
data.  They also have various associated exception classes which they
can throw.

The main program initialises one <float> instance say:  Matrix<float>
myMatrix(3, 3);
Then there is a second instance ie:  Matrix<float> mySecondMatrix(3,
3);  which appears further down the program listing ie:

Matrix<float> myMatrix(3, 3);

.....  Do some stuff here .....

Matrix<float> mySecondMatrix(3, 3);

...  More stuff....

Now:  This compiles & links fine in DJGPP C++ using RHIDE.  but when I
run it it gives me a "program exit code 255"  followed by all this
stuff:

Call frame traceback:
In function free+14
In function __builtin_delete+16
In functon __builtin_vec_delete+11
es.cpp(153) in function SetSize_t5Array1ZfUs
es.cpp(17) in function __t5Array1ZfUs
es.cpp(142) in function main
in function __crt1_startup+138


What have I done wrong???   It runs fine with one instance of the
Matrix, but for two, it crashes!!!
I have stepped through it using F8 and it always crashes right where the
second matrix is initialised.

HELP!
