Re: Segmentation Fault when trying to call zend_new_array.

Yes, it does. I recompiled php now with --configure --enable-embed=static and wrote a simple script: #include <stdlib.h> #include <stdio.h> #include "sapi/embed/php_embed.h" int main(int argc, char *argv[]) { php_embed_init(argc, argv); HashTable *ht = zend_new_array(15); return 0; } Compiled with the following command: gcc -I./Zend -I. -I./TSRM -I./main Zend/*.c TSRM/TSRM.c test-embed.c -ldl -lm -lphp7 -g The segmentation fault problem still occurs, when calling php_embed_init. Not sure if that's a problem of libphp7.so which I installed via apt or it is something related to a missing piece in the test-embed.c script I wrote?
