Bug #52686 mysql_stmt_attr_[gs]et arg. points to incorrect type
Submitted: 2010-08-24 13:37 UTC Modified: 2010-10-13 12:12 UTC
From: rein at basefarm dot no Assigned: mysql (profile)
Status: Closed Package: MySQLi related
PHP Version: 5.3.3 OS: Solaris10 on sparc
Private report: No CVE-ID: None

The 3. argument to mysql_stmt_attr_[gs]et() should be a pointer to my_bool or ulong depending on the value of its 2. arg. :-(  As of now the code always pass pointers to either my_bool or ulong, causing a bus error or incorrect value to be retrieved on a big-endian system like solaris/sparc.

A patch that fixes and tests this problem is coming.  Using the patch, the ext/mysqli/tests/mysqli_stmt_attr_[gs]et.phpt tests succeed for me on solaris10/sparc, solaris10/x86_64 and redhat4/x86_64, without it they fail on solaris10/sparc.

Btw, tested using mysql 5.1.35.  According to the mysql doc. the argument changed from an uint* to a my_bool* in mysql 5.1.7.
