Comment(by Xavi Gratal <gratal@…>):

 I forgot to say that I am using linux, and I tried this in both the Ubuntu
 Lucid Lynx alpha, which comes with gcc 4.4.3, and compiling gcc 4.4.3
 myself in Ubuntu Karmic Koala.

 As I said, the bug is triggered for the attaches source code only in gcc
 4.4.3, but the same problem appears in more complex programs also in the
 gcc 4.4.1 which ships with Karmic Koala.

 It happens both in boost 1.42.0 and 1.41.0. Actually I think the
 interprocess library didn't change between them.

 Looking at the code of interprocess, it doesn't seem a strict aliasing
 problem, and the code compiles without warning with -Wstrict-aliasing=2
 enabled.
