Hi,
Stephan reported that vcl when compiled with debug=t in aquavcl01 crashes. The
stack was very simply
- it crashed in the constructor of AquaSalBitmap, see bellow.
I identified that the problem is in vcl/aqua/source/gdi/salbmp.cxx. It crashes
in the constructor of
AquaSalBitmap which is declared as:
class AquaSalBitmap : public SalBitmap
{
public:
CGContextRef mxGraphicContext;
BitmapPalette maPalette;
basebmp::RawMemorySharedArray maUserBuffer;
basebmp::RawMemorySharedArray maContextBuffer;
sal_uInt16 mnBits;
...
Notice the usage of basebmp::RawMemorySharedArray. It looked suspect for us,
but we do not know of
any other place where it is used or how to use it properly.
The other question is why I'm now getting completely different stack here with
complete vcl debug=t
build:

Malloc warnigns looks suspect as well.

But nevertheless it is still connected with bitmap with splashscreen in this
case.
To reproduce:
1. compile complete VCL without debug:
cd vcl; build
Test application -> it works.
2. recompile everything with debug turned on:
rm -rf unxmac*pro; build debug=t
Application crashes.
3. touch aqua/source/gdi/salbmp.cxx
cd aqua/source/gdi; dmake
build debug=t
Application starts.
