[Pkg-chromium-maint] Bug#750584: chromium 35 for i386 is miscompiled - it crashes with SIGILL on SSE2 instructions

[Mikulas Patocka]

Package: chromium
Version: 35.0.1916.114-1~deb7u2
Severity: important

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?
Update of chromium from 34 to 35 in Debian Wheezy
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Run chromium
   * What was the outcome of this action?
Chromium crashes with SIGILL on SSE2 instruction
   * What outcome did you expect instead?
Chromium should work on processors without SSE2


I have AMD K6-3 processor. It doesn't have SSE or SSE2, it also doesn't have
CMOV instruction.

Chromium versions in Debian up to and including 34 work flawlessly on this
processor.

Due to some mistake, Chromium version 35 was compiled with SSE2 support,
consequently it crashes on K6-3 when it hits some SSE2 instruction. It crashes
on address 15e3381, the instruction is "xorpd  %xmm0,%xmm0"

Please, recompile chromium with -march=i486, so that it only contains 486
instructions, like all other packages in Debian i386 port.
