Bug #63258 [Csd]: seg fault with PDO and dblib using DBSETOPT(H->link, DBQUOTEDIDENT, 1);

Edit report at https://bugs.php.net/bug.php?id=63258&edit=1 ID: 63258 Updated by: ssufficool@php.net Reported by: paul dot visco at roswellpark dot org Summary: seg fault with PDO and dblib using DBSETOPT(H->link, DBQUOTEDIDENT, 1); Status: Closed Type: Bug Package: PDO related Operating System: centos 5.8 PHP Version: 5.4.7 Assigned To: ssufficool Block user comment: N Private report: N New Comment: Are you compiling against FreeTDS or Sybase libs? It looks like the segfault is in the DB LIB, not PHP. FreeTDS is passing a null pointer (or something invalid) to the libc strlen() function. To further debug this issue, FreeTDS will need to be recompiled with debug symbols intact, php recompiled and the segfault back trace reproduced. This will give better insight to the code generating the error.

I'm not sure why I used 1 instead of null for the parameter value. I have not posted patches since the source was moved to git. Please merge this change for me if possible. ------------------------------------------------------------------------ [2012-10-11 10:23:57] laruence@php.net ssufficool, do you have time to look into this? seems you intentionally change the "NULL" to "1" in https://github.com/php/php- src/commit/36b8c4cb thanks ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
