> Because the alignment of a member is dependent to the position in the struct in AIX platform according to the table in http://www.ibm.com/support/knowledgecenter/SSGH2K_13.1.2/com.ibm.xlc131.aix.doc/proguide/alignment.html
And on the -qalign and #pragma options, which do get used. The commercial product I work on needs to be compiled -qalign=natural on AIX, or it doesn’t work (I can explain the reasons if anyone's interested, but they're complex, boring, and hard to work around).
