[PHP-DEV] Bug #10879: odbc_prepare causes bus error From: ville.alkkiomaki <email protected>

Bug description: odbc_prepare causes bus error

Following script causes Bus error with php 4.0.5 & Solid 3.x (and at least 4.0.3 & 4.0.1pl2). It crashes identically as a standalone cgi binary and as a apache module.

<?php
error_reporting(255);
if($hdbc=odbc_connect("tcp localhost 1313","login", "password")) {
  if($hstmt=odbc_prepare($hdbc, "SELECT * FROM FX_USER WHERE LOGIN=?")) {
      if(odbc_execute($hstmt,array("user"))) {
        print("OK -- query completed with success\n");
      }
  }
  odbc_commit($hdbc);
  odbc_close($hdbc);
} else print("Connect to database failed.\n");
?>

Where odbc_prepare causes Bus error and gdb gives following backtrace when configured with "--with-solid --enable-debug".

#0 0xef6c7bb4 in ssa_stmt_getstmtintegerproperty ()
   from /usr/lib/libsocssx35.so

#8 0x24424 in main (argc=2, argv=0xeffffc6c) at cgi_main.c:730

Above script works fine with php 3.0.18RC1 & Solid 3.0 SDK. Older php3 releases had problems to compile with Solid 3.x, but if I recall right php version 3.0.1* had also similar problems. (required little hacking to compile)
