The plot thickens.
GCC 4.5.1 (stock) + Boost 1_44_0 (stock) on Fedora 14 x86-64: garbage
GCC 4.5.1 (stock) + Boost 1_47_0 (custom) on Fedora 14 x86-64: garbage
GCC 4.6.0 (stock) + Boost 1_46_1 (stock) on Fedora 15 x86-64: works
GCC 4.5.1 (custom) + Boost 1_44_0 (custom) on [custom] ppc-32: garbage
And a few other data points I had handy:
GCC 4.4.4 (stock) + Boost 1_39_0 (stock) on Fedora 12 ppc-32: works
GCC 4.5.1 (stock) + Boost 1_44_0 (stock) on Fedora 14 x86-32: garbage
So it looks like 4.5.1 does not play well with this code, at least not
Smaller test case available here:
For now, it looks like my workaround is to use the later compiler.
Not a huge deal, but if someone happens to be poking in the depths of
Boost.Interprocess and sees what's going on, I'd love to hear about
Thanks again for everyone's time and suggestions.
