That means it's almost certainly a bug in GDB.

Should, but this code is very tricky, to say the least.  And it's
sensitive to the exact version of the compiler in use.  Remind me, are
you using CVS HEAD?  And, I don't suppose you've got a smaller
testcase?

Failing that, could you post the readelf output for the entire
compilation unit containing Soi::Waypoint?  From the compilation unit
header all the way down to the next one.
