I hope this is an appropriate question for the list:
It is :)
Using project builder, my program runs through with no problems in
debug mode. When build and run (not debugging) I get a memory error
(signal 11 (SIGSEGV)).
Do you mean that you compiled your code without -g flag? If yes, try to
compile it with this flag set (it adds debug info wether the generated
machine code is optimized or not) and launch your program under gdb, it
should show you where the SIGSEGV occurs. If your program is not
launched under gdb, you may also have a look to the log trace, it tells
you in which thread and which function call this signal occured.
If you mean that the same code compiled with the same C flags works
well under debugger, and crashes when it runs by itself, then this may
be a pointer badly initialized which "luckily" points within your app
address space in the first case (under gdb), and outside in the second
case (running by itself). Using the log trace could give a help.
I believe that the error has something to do with my input IOProc used
in multiple calls to AudioConverterFillComplexBuffer.
What do you mean by "multiple calls to AudioConverterFillComplexBuffer"?
I can't pinpoint the error any further because it doesn't happen in
debug mode. Might this have something to do with the
Add_Load_To_IOProc preprocessor directive In Daisy's IOprocs?
I'm just looking for a pointer to where I find out about this stuff.
Thanks in advance.
