In EqualizationDialog you've declared mdBMax as a pointer to the
float and not the float itself.

Then in MakeEqualizationDialog you attempt to set the float, but
the pointer would be invalid as you've never allocated the storage
for the float.

Many ways to skin it, but you could...

change:
   *mdBMax = 30.;
to:
   mdBMax = 30.;

and:
   mFilterFuncR, mFilterFuncI, mWindowSize, mM, mdBMax,
to:
   mFilterFuncR, mFilterFuncI, mWindowSize, mM, &mdBMax,

Or you could just...

change:
   *mdBMax = 30.;
to:
   mdBMax = new float(30.);

(but you'll have to delete it later)
