Priority: medium
Bug ID: 80889
Assignee: mesa-dev@lists.freedesktop.org
Summary: draw_pipe_clip.c division by zero in interp
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: zec...@gmail.com
Hardware: x86-64 (AMD64)
Status: NEW
Version: 10.2
Component: Other
Product: Mesa
In draw_pipe_clip.c:166
"const float oow = 1.0f / pos[3];"
I found that running a geant4 example pos[3] is zero.
Unfortunately I do not remember which example ran.
I believe an "assert(pos[3]);" or equivalent should be put immediately before
to avoid a division by zero.
