#4837: check of shm_img pointer in ChromaKeyOSD::AllocImage() should be done
before shm_img is dereferenced
---------------------------------------------+------------------------------
Reporter: Erik Hovland <erik at hovland.org> | Owner: ijr
Type: defect | Status: new
Priority: minor | Milestone: 0.21
Component: mythtv | Version: 0.21-fixes
Severity: low | Mlocked: 0
---------------------------------------------+------------------------------
shm_img is dereferenced before it is checked:
{{{
uint size = shm_img->bytes_per_line * (shm_img->height+1) + 128;
X11U;
if (shm_img)
}}}
Which means the caller of this member function will segfault if the shm
call didn't work.
