March 2007 Print Figure 1 Figure 2 Figure 3 Figure segmentation fault error 139 4 Figure 5 Figure 6 Have you ever wondered what causes the mysterious "segmentation fault" failure messages on AIX*? Even with more applications being written as native 64-bit applications the occurrence of these failures seems to have increased. Underlying it all is the addressing mechanism used by AIX on PowerPC* and POWER* processor families, particularly in the

32-bit world. The problem is that memory is handled in 256 MB "chunks" called segments and paging is then overlaid on top of this. 32-bit code uses 16 segments to divide up its 4 GB of address space. 64-bit code uses the same mechanism but with 232 segments to choose there isn't really a problem. Segments identify the different types of uses of memory, and then pages provide a means of manipulating smaller pieces of memory within these segments. The segmentation mechanism used in AIX is similar to that plaguing the early days of PCs, except the segments were 64 K in PCs and are 256 MB in AIX. Whilst 256 MB seemed a huge amount when the segmentation mechanism was first designed, it isn't large by today's standards. In particular, it isn't large when one segment is put to multiple uses, with the Private Data segment (2) fitting the stack, heap and some shared objects into that 256 MB, with the stack and the heap movi
