Description:
------------
I'm using PHP 5.6.14, IBM Informix CSDK 4.10, PDO Informix 1.3.1. Always got Segmentation Error when insert something to table that have TEXT or CLOB datatype. Error from log : 

[Fri Oct 30 01:08:41.704142 2015] [core:notice] [pid 27963] AH00052: child pid 27967 exit signal Segmentation fault (11)

Before that at compile the pdo informix, no error only warnings when run the "make test" command. The warnings are like below :

[root@localhost PDO_INFORMIX-1.3.1]# make test

Build complete.
Don't forget to run 'make test'.
