If you upgrade to maintenance level 5300-03, that will include this

fix. Use the command "oslevel -r" to determine what maintenance level

On AIX 5.3 ML3 (e.g. maintenance level 5300-03), there is some problem

with the handling of the pointer to memcpy. It is speculated that

this relates to some linker bug that may have been introduced between

5300-02 and 5300-03, but we have so far been unable to track down the

cause.

At any rate, the following patch, which "unwraps" the function

reference, has been observed to allow PG 8.1 pre-releases to pass

regression tests.

The same behaviour (albeit with varying underlying functions to

"blame") has been observed when compiling with either GCC 4.0 or IBM

XLC.

The following patch works on the AIX 5.3 ML3 box here and didn't cause

any problems with postgres on the x86 desktop. It's just a cleaner

version of what I tried earlier.
