--- Comment #29 from Barto <mister.freeman at laposte.net> ---
like Roland said in comment#13 the bug could be in mesa source code, an
incorrect initialization of llvm 3.7.0,

it worked in 3.6.2, but perhaps in 3.7.0 the same code is not enough, it needs
maybe more precise instructions in order to target exactly the CPU platform, to
produce correct cpu opcodes,

in dmesg I can see these messages when the SIGILL occurs :

[13766.649327] traps: tunnel[4095] trap invalid opcode ip:7f68ce8d7183
sp:7fff6c078700 error:0

[35876.638782] traps: llvmpipe-1[8766] trap invalid opcode ip:f77271bd
sp:f3536db0 error:0
[35876.638785] traps: llvmpipe-0[8765] trap invalid opcode ip:f77271bd
