Description:
------------
Code is on a virtual host and it appears php was compiled with an obsolete version of aspell [.5]. This appears to be causing a fatal error if pspell_config_personal() is called. 

The error handler appears to send an empty error message to the client. And, pspell_config_personal() is not returning a binary response. 

All the other pspell() functions behave as expected with errors.

is_writeable('crcustom.pws') and file_exists('crcustom.pws') tests work fine on the pws file.

 

Reproduce code:
---------------
ini_set("display_errors", "on");
error_reporting(E_ALL);

$ps_config = pspell_config_create("en");

if(!pspell_config_personal($ps_config, $_SERVER['DOCUMENT_ROOT'] . "/dictionaries/crcustom.pws"))
    die("<div style=\"color:red; font-weight:bold\">Server spell function error. Could not open custom dictionary. Please report this error to the Webmaster.</div>");

if(!pspell_config_mode($ps_config, "PSPELL_FAST"))
    die("<div style=\"color:red; font-weight:bold\">Server spell function error. Could not configure. Please report this error to the Webmaster.</div>");

$dict = pspell_new_config($ps_config)
or die("<div style=\"color:red; font-weight:bold\">Server spell function error. Could not open the dictionary [$dict]. Please report this error to the Webmaster.</div>");

echo "Everything loaded OK";

Expected result:
----------------
"Everything loaded OK"

Actual result:
--------------
Blank client page if pspell_config_personal() is active.

"Everything loaded OK" if pspell_config_personal() is commented out.
