php script is generating segmentation fault in Solaris

 DearAll, 

The below php command runs on linux well and the output but in solaris we are getting the below error. 

Linux:

[root@kmefic-web-dev ~]# php -r 'echo iconv("UTF-8", "UTF-8", "Hello, world.\n");'

Hello, world. 

We are getting the result. 

But the same script is generating segmentation fault in Solaris. Please see below the result from Solaris.

 -bash-3.2$ php -r 'echo iconv("UTF-8", "UTF-8", "Hello, world.\n");'

Segmentation Fault (core dumped)

-bash-3.2$ su -

# php -r 'echo iconv("UTF-8", "UTF-8", "Hello, world.\n");'

Segmentation Fault - core dumped

Can you please anyone advice ?

Thanks & Regards
