ESQL-C INSERT Problem

Sascha Demetrio (sd@b-comp.de) reports a bug with a severity of 2
The lower the number the more severe it is.

Short Description
ESQL-C INSERT Problem

Long Description
An embedded SQL/C program INSERT operation fails, if a string value
submitted through a host variable ends with a backslash character.
This bug is not triggered if the offending variable is the last
variable in the INSERT statement.

Running the test program (below) results in the following output:

internal error: SQL error: Too many arguments in line 18.

The program works if you remove the trailing backslash from `f1'.

Version Info:
OS: Linux / glibc-2.1.3
PostgreSQL 7.0.2 on i586-pc-linux-gnu, compiled by gcc 2.95.2


Sample Code
Table:

CREATE TABLE t1 ( f1 CHAR(10), f2 CHAR(10) );

ESQL/C Code:

--BEGIN-FILE--
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

EXEC SQL INCLUDE sqlca;

int main(void)
{
  EXEC SQL BEGIN DECLARE SECTION;
  char f1[11];
  char f2[11];
  EXEC SQL END DECLARE SECTION;

  EXEC SQL WHENEVER SQLERROR GOTO sql_error;
  EXEC SQL CONNECT TO testdb;
  strcpy(f1, "something\\");
  strcpy(f2, "FOO");
  EXEC SQL INSERT INTO t1 ( f1, f2 )
  VALUES ( :f1, :f2 );
  EXEC SQL COMMIT WORK;
  EXEC SQL DISCONNECT;
  return 0;
sql_error:
  EXEC SQL WHENEVER SQLERROR STOP;
  fprintf(stderr, "internal error: SQL error: %s",
      sqlca.sqlerrm.sqlerrml
      ? sqlca.sqlerrm.sqlerrmc : "unknown error");
  EXEC SQL ROLLBACK;
  EXEC SQL DISCONNECT;
  return -1;
}
--END-FILE--
