<pre>I am using mesa 17.0.2. I am using Qt to render YV12 buffers.
If I set all Y values to "1", it renders correctly.
int index = 0;
for(int width=1;width<currentStatus->width;width++) {
for(int height=1;height<currentStatus->height;height++) {
data[index] = 0x00;
index++;
}
}
If I set all Y values to "0", I get a SIGSEGV.
int index = 0;
for(int width=1;width<currentStatus->width;width++) {
for(int height=1;height<currentStatus->height;height++) {
data[index] = 0x00;
index++;
}
}
Here is the crash backtrace.
