on bug 92214
from Barto
another discovery : in qemu I can set a type of CPU ( pentium, pentium2, pentium2, core2duo, SandyBridge and many more ), you can see the CPUs list with the command "qemu-i386 -cpu ?", until now I used the qemu option "-cpu host", which means that it's the CPU of the host who is emulated ( my pentium dual core E6800 ), then I decided to set a different CPU name in my qemu script : -cpu core2duo -enable-kvm -machine type=pc,accel=kvm -smp 2 with this setting the bug disapears, all is ok in my virtual machine, glxgears and all openGL programs can run without crash, the mesa driver llvmpipe doesn't crash, after that I decided to do set again another CPU in qemu : -cpu Penryn -enable-kvm -machine type=pc,accel=kvm -smp 2 \ with "Penryn" CPU the bug is back in my virtual machine, which means that the bug seems related to the type of CPU, llvm 3.7.0 lib may have a bug when he tries to generate binary code, it fails with some CPUs, this problem doesn't exist with llvm 3.6.2 lib
