Tom Lane 917fdbc633 Fix null-pointer crash in ECPG compiler. 
When compiling a DECLARE section containing a union nested
inside a struct, ecpg passes a null value for struct_sizeof to
ECPGmake_struct_type.  I (tgl) didn't foresee that case in
commit 0e6060790, and wrote an unprotected mm_strdup() call.
