And for the sample code, I can share you the php code if you want, but not the wsdl and xsd (private

Indeed, too few information. A backtrace[1] could be helpful, an
SSCCE[2] would likely be even more helpful.

Description:
------------
I got really few information on this crash:
When I try to call a function through soap client with WSDL_CACHE_NONE and SOAP_SSL_METHOD_TLS, I
got a segfault with soap.so, gdb send me those lines :
```
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Program received signal SIGSEGV, Segmentation fault.
