Well I tried a few things:
1. I wrote a stupid little prog. It does a simple multiplication in the style
you did in hashString.....main () { int j=25; j*=j+2; } and once again
.mul is called (.umul if the var is unsigned) .umul calls the _PROCEDURE_
LINKAGE_TABLE and there is the call to the same absolute address as
before: 0xef7c2f7c. I did with gcc and c89 (ansi c compiler).

Than I wrote a little mmap application that makes 2 mmaps like yours
one on 0xdf770000 and the following one at 0xef770000, after the 2nd mmap
a nice multiplication. I compiled this prog with both gcc and c89.
Exactly the same behavior, exactly the same problem: now I tend to believe
that is is a solaris libc problem/or a mmap problem whatever you want.

You could maybe as the gnu-compiler guys: they should really know!!!
