Do not have a minimal way to reproduce this, but when I did an unusual (for our team) compiler optimization, namely

(proclaim '(optimize (speed 3) (safety 0)))

I got this error when compiling:

Error:

    Unknown vinsn: CCL::GET-COMPLES-SINGLE-FLOAT
       [Condition of type SIMPLE-ERROR]

In:
    Backtrace:
      0: (CCL::NEED-VINSN-TEMPLATE CCL::GET-COMPLES-SINGLE-FLOAT #<HASH-TABLE :TEST EQ size 580/687 #x3020001CB97D>)

Robert Smith grepped for "comples" and found these hits in the sources:

compiler/reg.lisp:(defconstant hard-reg-class-fpr-type-comples-double-float 2)
compiler/X86/x862.lisp:                    (! get-comples-single-float reg result-reg)
compiler/X86/x862.lisp:                 (! get-comples-double-float reg result-reg)

Perhaps this shows a simple typo (comples for complex) and would be enough to at least fix something or figure out the error we're seeing.

The following log probably describes the bug fully. I'm not sure how to assign the priority, but this seems major to me. It occurs in 16119 but not in 15915.

It appears that sometimes (prog1 x y) returns y. I've attached a file where CCL returns an incorrect value, perhaps for that reason. Version/platform info is in that file, but here it is:

1.9-dev-r15527M-trunk  (LinuxX8664)

[and from uname -a:]

Linux sloth 2.6.32-45-server #100-Ubuntu SMP Wed Nov 14 11:02:27 UTC 2012 x86_64 GNU/Linux

As explained in the attached file, I didn't have this problem on a Mac for a slightly older CCL version.
