Any chance your first string is empty? Zeev Why yes, actually it is always going to be empty at least once. It is used inside of a loop, and just before the loop starts, the string is empty. The only way the string gets data is through add_string_to_string. Thanks.

Re: [PHP-DEV] concatenating strings
I am getting a SIGSEGV with this function. I am probably just missing something. I was hoping for a function with the prototype strcatl(zval **z, char *s, int l); strcat(zval **z, char *s); Lacking those, I tried zval **data; /* call to zend_hash_find to set data */ zval *tmp; MAKE_STD_ZVAL(tmp); ZVAL_STRINGL(tmp, s, l, 1); add_string_to_string(*data, *data, tmp); What am I missing?

Zeev I have managed to avoid the problem, now that I know that I can't have an empty string as the first op, so it works. Once I release the extension, I am sure that people will find ways optimize it, and having an add_string_to_string with will accept a null string will be one of them. Thanks.
