ECPG Segfault and variable usage question.

Hello,

this is a code snippet that causes ECPG to segfault. It's quite tricky
to produce, as changing the variable name from 'var' to 'myvar' already
causes things to compile fine ...

#define CHAR_LENGTH 25
myfunction ()
{
EXEC SQL BEGIN DECLARE SECTION;
char var[2*CHAR_LENGTH];
EXEC SQL END DECLARE SECTION;

EXEC SQL DECLARE mycursor CURSOR FOR
SELECT att1, att2
FROM mytable
WHERE att1 LIKE :var ESCAPE '\\';
EXEC SQL OPEN mycursor;
}

Stack trace was obtained using a snapshot from about 2 weeks ago, ECPG from
the 7.4.1 release segfaults also.

#0 0x4015fdcb in chunk_free () from /lib/libc.so.6
#1 0x4015fc53 in free () from /lib/libc.so.6

stmt=0x80c14f8 "declare mycursor cursor for select att1 , att2
from mytable where att1 like ? escape '\\\\' ", mode=0, con=0x0) at

#6 0x401089ed in __libc_start_main () from /lib/libc.so.6

Another problem that's giving me headaches trying to find a workaround for
is the following use of variables as data sources in INSERT/UPDATE
statements:

:myarray[index[10]]

Any comments, suggestions, hints ? Thanks a lot,

Jürgen
