This appears to be a bug in the compiler. In the case you indicate, it is using LDW to read the "pointer" structure member when LDNW should be used instead. I filed SDSCM00047774 in the SDOWP system to have this addressed. Please feel free to follow it with the SDOWP link below in my structure.

That's because #pragma pack is not supported in version 7.3.x. That feature is introduced in version 7.4.0.
