Public bug reported:

My CPU does not support SSE2, this is a fact.

And as far as I knew, there was nowhere a *requirement* listed that for the use of Chromium, a SSE2-capable CPU would be mandatory.
For instance, old(er) Athlon XP machines support SSE, but not SSE2.

I've run a DEBUG build of chromium v41 to demonstrate this fact.

These are the most evident 2 lines:

#
# Fatal error in ../../v8/src/ia32/assembler-ia32.cc, line 82
# CHECK(cpu.has_sse2()) failed
#

Looks to me that the _asm routines _blindly_ assume that the CPU is capable of SSE2 instruction set.
At least the browser should exit more gracefully if this is the case, but not crash with a SIGILL.
