Specific builder creating Asterisk builds with "invalid opcode"

[Anthony Messina]

I have a small private Koji setup here which has worked well for quite
some time.  I have only two builders, both running up to date x86_64
Fedora 16.  I am having a strange issue where when I build Asterisk 10
for Fedora 15 x86_64 on one of the builders, Asterisk will fail to start
with an invalid 'opcode message'.  However, If I build it on the other
builder, Asterisk will work as expected.

I am truly not sure where to begin, but I've only seen this issue start
to occur within the last month or so.

The only real difference between the two builders are the CPUs.  Showing
the first of each below, the builder that produces Asterisk builds which
fail is:

~]# cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 42
model name      : Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
stepping        : 7
microcode       : 0x25
cpu MHz         : 1600.000
cache size      : 8192 KB

core id         : 0

And the builder that produces a working Asterisk build is:
~]# cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 15
model           : 6

stepping        : 4

cpu MHz         : 2800.000
cache size      : 2048 KB

The (first) CPU of the Fedora 15 x86_64 system on which I am attempting
to run the Asterisk build is:
~]# cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 15

As I said, I'm not even sure where to begin, so I'm not sure that
information is helpful.

The build log which creates the inoperable Asterisk:
[1080956.984634] asterisk[2294] trap invalid opcode ip:516e52
sp:7fffcfef3600 error:0 in asterisk[400000+197000]
is here:
http://messinet.com/~amessina/asterisk_invalid_opcode_build.log

The 'good' build log is here:
http://messinet.com/~amessina/asterisk_success_build.log

The spec file is 99.9% the same as Jeffrey Ollie's official Fedora spec
file and is here:
http://messinet.com/~amessina/asterisk.spec

Thanks in advance for your help.  -A
