State-Changed-Why:
Igor created a small test case which displays the behavior he considers a bug and included an analysis of the failure. I will add only one comment: because a feature is hard to use in a complex program does not imply that the feature has incorrect behaviour. In this case, #pragma pack came from a C ABI. It is doubtful anyone ever looked at the rules as applied to C ++. E.g. no documentation on such interactions is found in tm.texi. One correct resolution to this PR is to update our documentation. (I will also add another user-level fix.)
