<pre>Issue is reproducible on my laptop:
OS: Ubuntu 17.10 64-bit
CPU: Intel® Core™ i7-7500U CPU @ 2.70GHz × 4
GPU: Intel® HD Graphics 620 (Kaby Lake GT2)
mesa: 18.1.0-devel (git-7d4007d58a)
kernel: 4.13.0-31-generic
In dmesg I noticed this message after firefox crash:
[23838.361098] traps: Web Content[30658] trap divide error ip:7f6dee287e9f
sp:7ffc7d493f20 error:0 in i965_dri.so[7f6dedf27000+8dd000]
Additionally I run firefox with gdb and got following error message:
Thread 1 "Web Content" received signal SIGFPE, Arithmetic exception.
0x00007f18ffe87e9f in evaluate_idiv (num_components=1, bit_size=<optimized
out>, _src=_src@entry=0x7ffc0c2fb620) at nir/nir_constant_expressions.c:8791
8791 int32_t dst = src0 / src1;
(gdb)
Continuing.
At this point src1 equals to zero.</pre>
