well, that didn't work.
I guess I'll setup another box with boost 1.58 - don't think I've tried that one yet ...

thanks

The issue is nothing to do with boost or any other library version ... it actually is caused by a slight calculation difference between SSE (used in 64-bit builds) and x87 FPU (used in 32-bit builds).

Try running configure again (after a make clean) with the following:

Code:

CFLAGS="-O2 -mfpmath=sse -msse2" CPPFLAGS="-O2 -mfpmath=sse -msse2" ./configure

This will force the compiler to use SSE for all floating point maths, instead of the x87 FPU (which is default for 32-bit). It does mean you need a processor with SSE2 support, but I'd be surprised (er, shocked actually) if you don't have that.
