Hi,

String array type in ecpg is strange.

> pgbash
pgbash> create table test_array(code varchar(4), name text[3]);
pgbash> insert into test_array values('c01','{"n01","n02","n03"}');
pgbash> select * from test_array;
code|name
----+-------------------
c01 |{"n01","n02","n03"}
(1 row)

--------------------( ECPG program)------------------------
# include <stdio.h>
exec sql include sqlca;

main()
{  exec sql begin declare section;  char   code[5];  char   name[256];  exec sql end   declare section;
  exec sql connect to admin user admin;
  exec sql declare cur cursor for select * from test_array;  exec sql open cur;  while(1)  {     exec sql fetch cur
into:code, :name;     if( sqlca.sqlcode == 100 ) break;     printf("# code=(%s) name=(%s)\n", code, name );  }  exec
sqlclose cur;
 
}
------------------------------------------------------------

Results are as follows.

# code=("n02","n03"}) name=({"n01","n02","n03"})
Segmentation fault (core dumped)



Here is the patch which corrects this bug.
