Is this fix included in the 8.1.6.2 patch?

I was curious enough to call Oracle about this, after I didn't find anything on Metalink about it. FYI:

It's a legitimate bug (1084273/1227119) that is Solaris-specific. There is a patch available for it outside of 8.1.7, however. The patch is available on oracle-ftp.oracle.com under /server/outgoing/SUN_SOLARIS2/BUG1227119

The analyst said that the patch is for the 32-bit version, and is checking to see if the patch needs to be applied to the 64-bit version as well.
