I have build the package and installed it and run the one of the supplied testcases.

I am using v9.7fp11_linuxx64_dsdriver against a iSeries V7.

The ibm_db2 works fine with the same driver.

Test script:
php tests/fvt_001_DbConn.phpt
pdo_ibm: Connect to database
Segmentation fault (core dumped)

Expected result:
To work :-)

Actual result:
Segmentation fault (core dumped)

I have fixed the error. See patch file.
Also on ubuntu 16.04 config.m4 has problems finding php_pdo_driver.h. By adding the following solves the problem.

65 + elif test -f $phpincludedir/ext/pdo/php_pdo_driver.h; then
66 +      pdo_inc_path=$phpincludedir/ext

Is this still an issue with the latest PDO_IBM (1.4.1)?
