Recently in AIX environment, using esql to compile ec/ecpp formed.o and xlc/xlC to compile ordinary c/cpp formed.o connection, runtime found that different.o calls pass struct structure parameter access will be misplaced.

Excluded the program itself, the final discovery is AIX under esql and xlc compilation default structure alignment compilation parameter settings are different.

When esql is compiled, you can use esql -v to see that-qalign=nature, and according to xlc help, the default-qalign=power, the two are different.

Since the.o compiled from esql is already in use in other projects, we modified the makefile of c/cpp, added the parameter-qalign=nature, and recompiled the connection to solve this problem.
