[Stk] unhandled exception when using BlitSaw with std::vector

[Nick Dika]

Thanks Stephen. Here's a simplified version of what I'm doing.

This works:

stk::BlitSaw oscArray[10];

for( int i=0; i < 10; i++ )
{
stk::BlitSaw saw;
saw.setHarmonics(0);
saw.setFrequency(220);
oscArray[i] = saw;
}

This breaks:

std::vector<stk::BlitSaw> oscs;

for( int i=0; i < 10; i++ )
{
stk::BlitSaw saw;
saw.setHarmonics(0);
saw.setFrequency(220);
oscs.push_back(saw);
}

the second example causes an unhandled exception/access violation reading
from a location. As mentioned this appears to happen after
StkFrames::resize() is called (I don't fully understand why this would be
called).

thanks, n
