This bug now shows up in release testing for 1.41; c.f. http://www.boost.org/development/tests/release/output/Debian-Sid-boost-bin-v2-libs-fusion-test-adapt_assoc_struct-test-gcc-4-4-debug-sequence.html

Also reported as a Debian bug: ​http://bugs.debian.org/550300

This would be nice to fix for 1.41.

Thanks, -Steve

I checked in a fix to the trunk. The release branch was already fixed.
