ecpg with nested structure

Hello,

while porting an application from CA/Ingres to PostgreSQL
I came across a segmentation fault by ecpg. The code looks
something like this:


EXEC SQL BEGIN DECLARE SECTION;
struct bnd_a
{   struct bnd_b   {char myvar[31];   } bnd_b[5];
} bnd_a[5];
EXEC SQL END DECLARE SECTION;

myfunction()
{   EXEC SQL DECLARE mycursor CURSOR FOR     SELECT mycolumn FROM mytable;   EXEC SQL OPEN mycursor;   EXEC SQL FETCH
mycursor    INTO :bnd_a[0].bnd_b[0].myvar;   EXEC SQL CLOSE mycursor;
 
}


Versions are:

ecpg (PostgreSQL 7.4) 3.0.0
Linux scaleo 2.4.18-4GB #1 Wed Mar 27 13:57:05 UTC 2002 i686 unknown

Are nested structures not supported by ecpg ?

Thanks for any information,
