Package: chromium
Version: 37.0.2062.120-1~deb7u1
Severity: important

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

   * What led up to the situation?
Update to Chromium 37 in Debian Wheezy
   * What exactly did you do (or not do) that was effective (or
Run chromium
   * What was the outcome of this action?
Chromium crashes with SIGILL on CMOV instruction
   * What outcome did you expect instead?
Chromium should work on i586-class processors, like the other programs in
Debian i386 port

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

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

Due to some mistake, Chromium 37 was compiled with SSE and CMOV instructions,
consequently it crashes on K6-3 on illegal instruction signal. (chromium 35 was
compiled with SSE2 instructions, I filed another bug report for that earlier)

Please, recompile chromium with -march=i586, like other packages in Debian i386
