I am almost dead sure that this is the case now. I had an original bit of
code that went<br>
<br>
if(pMidiOut[dev_num])<br>
{<br>
pMidiOut[dev_num]->SetTxReady(false);<br>
}<br>
<br>
if ((io_in_data & DIAG_MESSAGE_MASK) == DIAG_MESSAGE_MASK)<br>
<br>
and it crashed big time.<br>
I changed the code to<br>
<br>
if ((io_in_data & DIAG_MESSAGE_MASK) == DIAG_MESSAGE_MASK)<br>
{<br>
if(pMidiOut[dev_num])<br>
{<br>
pMidiOut[dev_num]->SetTxReady(false);<br>
}<br>
.... etc<br>
}<br>
else<br>
{<br>
if(pMidiOut[dev_num])<br>
{<br>
pMidiOut[dev_num]->SetTxReady(false);<br>
}<br>
.... etc<br>
}<br>
<br>
and it worked fine. So I believe it is definitely something to do with the
alignment of the code.<br>

is still there, however, the results vary depending upon what I do within
the code. I believe that it has something to do with the way the code is
packed and aligned. If I remove a single line of code in a function such
as a comparison, the program may go into this infinite exception loop. If
I remove a line of code else where, the tasks may return that they have started,
but the tasks don't actually start running (I added some diag code to show
me when the actual task function is entered). I add a line of code somewhere
else, such as a cout, ant the program runs fine. It may have something to
do with the linking, causing the code to jump to an incorrect address.<br>
