ios 6 crashes

[bogardon]

there seems to be a crash, can someone look into it? I'll come back with more information later.

Can you be more precise? Is it the test program or another one?
It has been tested recently with iOS6 and I did not see any issue, so more informations would be welcome!

im sorry i forgot to mention that i attempt to "normalize" images before running stackblur via the method described here:

http://stackoverflow.com/questions/2457116/iphone-changing-cgimagealphainfo-of-cgimage

and doing so causes a crash. the reason why i had to normalize id also described in the link.

xcode point to this with bad access:

for (y=0;y<h;y++){
// m_PixelBuf[yi]=0xff000000 | (dv[rsum]<<16) | (dv[gsum]<<8) | dv[bsum];
int offset=yi*4;
m_PixelBuf[offset]=dv[rsum]; // THIS IS WHERE BAD ACCESS HAPPENS
m_PixelBuf[offset+1]=dv[gsum];
m_PixelBuf[offset+2]=dv[bsum];

Are you sure you have the latest code? I used to have the exact same issue but it was fixed in 814e37e

I am also having this problem with iOS6 despite downloading the latest version. I get:

        routsum+=sir[0];
        goutsum+=sir[1];
        boutsum+=sir[2];

        rinsum-=sir[0];
        ginsum-=sir[1];
        binsum-=sir[2];

        yi++;
    }
    yw+=w;
}    // THIS IS WHERE BAD ACCESS HAPPENS

I was able to fix it in my case by retaining the image I was sending in to StackBlur, then releasing it afterwards:

UIImage *blurredImage = [[startingImage retain] stackBlur:blurRadius];
[startingImage release];

It was an image that should not have needed an additional retain call, and this problem has only appeared in iOS6.

I know this thread is closed, but I would like to open it again as there still seem to be crashes with regards to iOS6.
I got a crash at line
for (x=0;x<w;x++){
rinsum=ginsum=binsum=routsum=goutsum=boutsum=rsum=gsum=bsum=0; <== EXC_BAD_ACCESS
yp=-radius*w;

The solution I used was mentioned on this page.
http://iphonedevsdk.com/forum/iphone-sdk-development/108072-exc_bad_access-in-ios-6-but-not-in-ios-5.html

I made the following change
CFMutableDataRef m_DataRef = CFDataCreateMutableCopy(0, 0, CGDataProviderCopyData(CGImageGetDataProvider(inImage)));

Thanks, I'll check this and post an update quickly

Stackblur is crashing for me aswell. Here is a report from crashlytics http://i.imgur.com/WygWCGt.png
