[Bayes++] Segmentation fault with gcc 4.1

[Nicola B. <nb...@es...>]

Hello,

I have recently installed Linux on a new laptop with an Intel Core 2 Duo 
processor. After compiling the last version Bayes++ (2003.8-6), I had a 
segmentation fault when I tried to run the sample PV_SIR.
With a little of backtrace, I discovered the cause was the gcc 
option '-fstrict-aliasing', included in the '-O2' optimization. Removed that 
option and inserting manually all the others included in '-O2' and '-O3', the 
program run successfully.
It's not clear to me whether the problem is on gcc, kernel or Bayes++.

The gcc I use is the following:
gcc (GCC) 4.1.1 20061011 (Red Hat 4.1.1-30)
Copyright (C) 2006 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

This is the kernel version;
2.6.18-1.2849.fc6 #1 SMP Fri Nov 10 12:45:28 EST 2006 i686 i686 i386 GNU/Linux

Cheers,

Nicola
