Severity: important

Dear Maintainer,
After upgrading to php 5.4.34, a script running a query on a Sybase ADS
server using the libadsodbc driver from Sybase fails with errors like
this:
PHP Fatal error: Out of memory (allocated 524288) (tried to allocate
12415340535808218625 bytes) in SybaseClass.php on line 127
The error occurs on a line running odbc_exec().
It is produced because, now, php queries the returned column length
using the SQL_DESC_OCTET_LENGTH attribute which is not supported by the
underlying ODBC driver. As php doesn't check the return code, it tries
to use the uninitialized size to allocate the memory.
I already reported this bug upstream with a patch:
