Odd pspell issue

dstonek

$pspell_config = pspell_config_create("es");
pspell_config_ignore($pspell_config, 4);
pspell_config_personal($pspell_config, "/path to/my_dictionary.pws");
$dictionary_link = pspell_new_config($pspell_config);
if (!pspell_check($dictionary_link, $word)) { 
	$suggestions = pspell_suggest($dictionary_link, $word);  

}

By chance I found that certain word originated pspell_suggest error 500 (internal server error)
This is '-cenas'
I have no problem with these strings: 'cenas', 'cena', '-cena' and other random -word I tested.
Why that odd error
Thank you

I couldn't solve this problem yet.
Php 5.1.16
I check for similar words in case the keyword is not found in my dictionary to let users select an alternative

$pspell_config = pspell_config_create("es"); 
pspell_config_ignore($pspell_config, 4);  

pspell_config_personal($pspell_config, "/path-to/dictionary.pws"); 
$dictionary_link = pspell_new_config($pspell_config);         

if (!pspell_check($dictionary_link, $word)) {  

    $suggestions = pspell_suggest($dictionary_link, $word);   

}

99+% times it works as expected but pspell_suggest get into error 500 sometimes.

Examples:
1veja -> error
2veja -> error
2vejastro -> no error
5veja -> no error
12veja -> no error
veja1 -> error
veja5 -> no error
bo0las -> error
bo0las -> error
bo5las -> error
bo15las -> no error
5bolas -> error

Any help would be appreciated,
Thank you.

It would help if you post the actual error you get...

Hi!
To be sure it is a pspell_suggest problem, I added pair of mail('me',....) just before and after this function. First mail is always received but the second one isn't in those cases.

Web browsers: Internal Server Error
httpd error log (my test):

[Sun Aug 14 09:47:19 2011] [warn] (104)Connection reset by peer: mod_fcgid: read data from fastcgi server error.
[Sun Aug 14 09:47:19 2011] [error] [client XXX.50.78.197] Premature end of script headers: file.php

I think I found something like a pattern (there are inclusions and exclusions)
SOME plurals and an intercalated single number in 5 letters words.
'5bolas', 'bo5las' and any string with '5' in any position of 'bolas' get the error.
'5vejas', '0vejas', 'vej0as', 'monos6', '3cocos', '0pitos', 'bocas6'
Without the number, almost all these samples belong to my dictionary but 'vejas'
Strangely, 'vejas' and 'veja' does not get any suggestion while '12vejas' shows 10 good ones like 'ovejas' (sheeps).
Some exceptions: 'pinos', 'nubes'. Anywhere you add a number you get good suggestions

Thank you.

Well, it seems I found a kind of solution: adding a white space at the beginning o ending of the word.
Results are no exactly the same but differences are disposable.
There's a thing to care about: ask for pspell_suggestion only if the word is not in your dictionary. Adding a blank space before a know word would end in an error 500.
Examples:
'co0cos' and '0cocos' are not in my dictionary, they return an error 500
' co0cos' and ' 0cocos' are not in my dictionary, they return good suggestions arrays
'cocos' is in my dictionary so pspell_suggestion is not applied
' cocos' is not in my dictionary and it returns an error 500 !!!

I also recommend to only add a blank space in cases your string contains one digit number. There are no words mixing letters and numbers.
