aix gcc compile on aix 5L but couldn't run on aix 4.3

[Eli Ben-Shoshan]

AIX5.2 is significantly different from 4.3 and earlier 4.x version of 
AIX. Specifically the memory allocation techniques are different which 
might be why you are getting these messages. Are you compiling this app 
with a -m64 option? If so, then you will not be able to run this on a 
32bit box. Are you using any of the -march or -mcpu options to gcc. 
There are quite a few variations of the PowerPC architecture and I have 
found that if I compile with the -march flag on one machine it does not 
tend to work well (read: at all) on a different machine of another arch. 
Hope this helps.
