From a fresh trunk launch of the 64-bit intel IDE (Clozure CL64) execute:

(require 'webkit)

which will load the webkit example from the ccl:examples directory.

when webkit is done loading, execute:

(ccl::browser-window "http://www.apple.com")

this will drop you into AltConsole with the following error and backtrace, etc. that appears to be related to JavaScript execution. NB, this same series of steps does not error under the 32-bit intel IDE (Clozure CL32).

[4160] Clozure CL kernel debugger: 

I get the following return values from INTEGER-DECODE-FLOAT. (Version 1.4-r13122 (WindowsX8632))

? (integer-decode-float 0s0)
0
-150
1
? (integer-decode-float 0f0)
0
-150
1
? (integer-decode-float 0d0)
0
-1074
1
? (integer-decode-float 0l0)
0
-1074
1

In contrast:

? (decode-float 0s0)
0.0
0
1.0
? (decode-float 0f0)
0.0
0
1.0
? (decode-float 0d0)
0.0D0
0
1.0D0
? (decode-float 0l0)
0.0D0
0
1.0D0

CLHS states that INTEGER-DECODE-FLOAT returns "the same last two values that are returned by decode-float". Observed behavior seems otherwise.
