  • Ticket #7740 – Description

    initial v1

    33Opening the attached photo (a picture of my yard if you are wondering) which is more than 8000 pixels wide will always crash ShowImage from r42239 (and before, I've seen this for a while on big images.)

     5Edit: '''WARNING''': this image also causes very bad behavior in WebPositive, maybe due to the same bug!!! I would try downloading it with wget!

    57After much printf debugging I narrowed it down to BBitmap::_InitObject failing to clone an area from app_server. BBitmapStream::WriteAt just doesn't check the bitmap InitCheck like it should (that is another bug which I can fix) and then tries to access the bitmap Bits() which are null, causing a segfault. My backtrace is also attached, but the line numbers are probably wrong due to my added printfs. But this should be reproducable with the attached image.
