Hi!

The following code using CGAL library fails with runtime exception:
http://pastebin.ca/2160795

the exception:

$ ./cppgraham 
terminate called after throwing an instance of 'CGAL::Assertion_exception'
  what():  CGAL ERROR: assertion violation!
Expr: -CGAL_IA_MUL(-1.1, 10.1) != CGAL_IA_MUL(1.1, 10.1)
File: /usr/include/CGAL/Interval_nt.h
Line: 160
Explanation: Wrong rounding: did you forget the  -frounding-math  option
if 
you use GCC (or  -fp-model strict  for Intel)?

I am running this on 64-bit debian.	

Makefile looks like this:
g++ -o ${@} graham_scan.cpp -std=c++0x -lCGAL -lgmp

What's interesting is that the very same code runs ok on 32-bit debian
system.

Any ideas?

With best regards,
Dmitry
