| Summary | SIGFPE with cogl GL client in wayland |
| Severity | normal |
| Classification | Unclassified |
| OS | All |
| Reporter | bugzilla@hadess.net |

| Status | NEW |
| Version | unspecified |
| Component | Drivers/DRI/R600 |
| Product | Mesa |
I'm working with (mostly) the standard Fedora 18 packages for wayland/weston.
mesa-dri-drivers-9.0.3-1.fc18.x86_64
mesa-libEGL-9.0.3-1.fc18.x86_64
mesa-libwayland-egl-9.0.3-1.fc18.x86_64
1. Rebuild wayland (to get an updated libwayland-client, otherwise it crashes
when connecting to the display, not necessary on rawhide apparently)
2. Rebuild cogl with wayland support (add --enable-wayland-egl-platform to the
configure args)
3. Run weston &
4. Run this simple cogl example:
COGL_RENDERER=egl_wayland libtool --mode=execute gdb --args
./examples/cogl-crate
Program received signal SIGFPE, Arithmetic exception.
