[php-maint] Bug#789702: Bug#789702: php5: SOAP when throwing exception server side causes Segmentation Fault

[Joshua Dennis]

I installed 5.6.10 following the instructions with the link you provided.  It yielded the exact same results.  I’d really like to see this bug fixed, but unfortunately I won’t be able to devote any more time to this currently to start a whole other bug reporting process through PHP directly.
