I compile the following example :

#include iostream.h
#include sqlca.h
#include string

using namespace std;

EXEC SQL BEGIN DECLARE SECTION;
sql_context hctx;
EXEC SQL END DECLARE SECTION;

int main(int argc, char *argv[[]])
{

cout << "LEAK DETECTION TEST" << endl;

EXEC SQL ENABLE THREADS;

EXEC SQL CONTEXT USE DEFAULT;

cout << "Try 50 context allocate - context free" << endl;

int i = 50;
while (i < 1)
{

EXEC SQL CONTEXT ALLOCATE :hctx;

EXEC SQL CONTEXT USE :hctx;

EXEC SQL CONTEXT FREE :hctx;

++i;
}



}

It works but the the instruction "EXEC SQL CONTEXT FREE " seems to create
a problem of memory deallocation.

Question : How I can do to avoid the problem ?

Thanks in advance !!

I am not working on Solaris, and I do not have memory allocation problems.

Anyway, I think you should have an array of sql_context, and allocate each one:

sql_context hctx[[50]];

...

EXEC SQL CONTEXT ALLOCATE :hctx[[i]];
EXEC SQL CONTEXT USE :hctx[[i]];
EXEC SQL CONTEXT FREE :hctx[[i]];

And, check what happens if you add an instruction between CONTEXT USE and CONTEXT FREE. An EXEC SQL CONNECT.

This works fine on NT.
