Previous Comments: ------------------------------------------------------------------------ [2005-09-12 08:44:55] sniper@php.net It crashes for me too. I also have (a|p)spell 0.50.5 ------------------------------------------------------------------------ [2005-09-11 20:25:28] nlopess@php.net I've tested with aspell 0.50.5 and it produces the following (without my patch): http://mega.ist.utl.pt/~ncpl/php_aspell_valgrind.txt http://mega.ist.utl.pt/~ncpl/php_aspell_gdb.txt My patch fixes these problems. And it makes sense. PHP is passing a Speller* pointer, where it should be passing a Config* to pspell_manager_config(). I've "wasted" a couple of hours tracking down this bug in the aspell sources, and I think that this bug might not happen in all setups, depending on the compiler (because of some magic C++ upcasting). ------------------------------------------------------------------------ [2005-09-11 19:07:06] iliaa@php.net I've used pspell extensively with 0.5 lib and never seen a crash pertaining to the demonstrate code. ------------------------------------------------------------------------ [2005-09-10 14:49:02] nlopess@php.net Description: ------------ The pspell extension segfaults with (at least) aspell 0.50.x. Although aspell 0.60.x doesn't, there is a problem in PHP code. Patch: http://mega.ist.utl.pt/~ncpl/php_pspell_patch.txt Reproduce code: --------------- all pspell_config_xx() segfault. <? $p=pspell_new('en'); pspell_config_mode($p, PSPELL_FAST); ?> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34456&edit=1
