using the following piece of code :
.
.
/* 8 bit LUT (8 bit color and alpha lookup from palette) */
desc.pixelformat = DSPF_LUT8;
desc.caps = DSCAPS_NONE;
desc.flags = DSDESC_WIDTH |
DSDESC_HEIGHT |
DSDESC_PIXELFORMAT |
DSDESC_PREALLOCATED |
DSDESC_PALETTE;
desc.width = w;
desc.height = h;
desc.preallocated[0].data = &pixelArray[index];
desc.preallocated[0].pitch = scansize;
desc.preallocated[1].data = NULL;
desc.preallocated[1].pitch = 0;
/* swap the palette entries */
for (i = 0; i < length; i++)
{
register unsigned int tmp = rgbArray[i];
rgbArray[i] = (tmp >> 24) |
(tmp << 24) |
((tmp >> 8) & 0x0000ff00) |
((tmp << 8) & 0x00ff0000);
}
desc.palette.entries = (const DFBColor *)rgbArray;
desc.palette.size = length;
err = dfbMain->CreateSurface(dfbMain, &desc, &tempSurf);
.
.
.
a crash appears with a null mutex to lock, and here is the call stack:
0x84c1e8be in mutex_lock (mp=0x0)

This crash appears only if I restart my program about 10 times (initializing
and deintializing the DFB). and I can't locate who is corrupting the mutex.
does any body have idea about this?
regards.
