I'm trying to use the portaudio bindings and can't seem to call 
Pa_OpenStream, I get this error:

------------
source/pa_test.d(156): Error: function 
deimos.portaudio.Pa_OpenStream (void** stream, 
const(PaStreamParameters*) inputParameters, 
const(PaStreamParameters*) outputParameters, double sampleRate, 
uint framesPerBuffer, uint streamFlags, extern (C) int 
function(const(void)* input, void* output, uint frameCount, 
const(PaStreamCallbackTimeInfo)* timeInfo, uint statusFlags, 
void* userData) streamCallback, void* userData) is not callable 
using argument types (void**, PaStreamParameters*, 
PaStreamParameters*, double, uint, uint, extern (C) int 
function(const(void)* inputBuffer, void* outputBuffer, uint 
framesPerBuffer, const(PaStreamCallbackTimeInfo)* timeInfo, uint 
statusFlags, void* userData), void*)
------------

for clarity, here are the argument lists separated: what I need 
is up top, what I have is on the bottom:

(void**, const(PaStreamParameters*), const(PaStreamParameters*), 
double, uint, uint, extern (C) int function(const(void)*, void*, 
uint, const(PaStreamCallbackTimeInfo)*, uint, void*), void*)

(void**, PaStreamParameters*, PaStreamParameters*, double, uint, 
uint, extern (C) int function(const(void)*, void*, uint, 
const(PaStreamCallbackTimeInfo)*, uint, void*), void*)

--------------

The only difference I see is in const(PaStreamParameters*) but I 
feel like every time I pass a non-const argument where a const is 
required, the conversion should be implicit. At least, that's the 
way I seem to recall it working.

What am I doing wrong?

Here's the new argument lists:

(void**, const(PaStreamParameters*), const(PaStreamParameters*), 
double, uint, uint, extern (C) int function(const(void)*, void*, 
uint, const(PaStreamCallbackTimeInfo)*, uint, void*), void*)

(void**, const(PaStreamParameters*), const(PaStreamParameters*), 
double, uint, uint, extern (C) int function(const(void)*, void*, 
uint, const(PaStreamCallbackTimeInfo)*, uint, void*), void*)

They're identical... unless I'm losing my mind. Yet still its 
"not callable using argument types"

Have you tried the switch -vcolumn ? Maybe it'll point the 
location of the problem in a more accurate way. Just an idea.

I would suggest removing each parameter from the function prototype and 
call, until you find the culprit. Then put everything else back in. Try 
moving the parameters around.

Yes, the compiled code won't work, but this looks to me like a compiler 
bug (at least a diagnostic issue), and it will help narrow down a simple 
case you can submit.
