Hello George
Thank you for reporting of SDSCM00047774. I understand support version for #pragma pack.
I tried the __attribute__ ((__packed__)) in CGT7.3.x. As Nobuhiro said above, v7.3.8 or later ran correctly, but v7.3.7 or earlier didn't.
I expect that the problem of SDSCM00047774 can be resolved at an early stage. Would it be possible for you to tell me the release timing of fixed version?
Regards
