Finally got time to look at the problem with embeding the PHP interpreter in
D.
Again, the program runs just fine when compiled with -g but raises an
AccessViolation error on the php_embed_init() call. Here's the source code.
const int SUCCESS = 0;
extern (C)
{
int php_embed_init(int argc, char** argv , void**** ptsrm_ls);
void php_embed_shutdown(void*** tsrm_ls);
export char* get_zend_version();
}
int main()
{
static char *argv[2] = ["test1", null];
static void*** tsrm_ls = null;
if (SUCCESS != php_embed_init(1, argv, &tsrm_ls))
{
printf("Failed initializing php_embed sapi\n");
return -1;
}
printf("Zend version: %s\n", get_zend_version());
php_embed_shutdown(tsrm_ls);
return 0;
}
Following the advice from Walter, I've disassembled the files but given my
poor skills in ASM I've lost track just from the start so I ask for help
now.
The main function got translated to:
Comdat: __Dmain SEGMENT NONE '_TEXT' 00000052 bytes
0000 55 push ebp
0001 8B EC mov ebp,esp
0003 68 04 00 00 00 push offset L$8
0008 68 08 00 00 00 push offset L$2
000D 6A 01 push 0x00000001
000F E8 00 00 00 00 call _php_embed_init
0014 83 C4 0C add esp,0x0000000c
0017 85 C0 test eax,eax
0019 74 14 je L$9
001B 68 10 00 00 00 push offset L$3
0020 E8 00 00 00 00 call _printf
0025 B8 FF FF FF FF mov eax,0xffffffff
002A 83 C4 04 add esp,0x00000004
002D 5D pop ebp
002E C3 ret
That's the debug version. The optimized one doesn't have the following lines
0000 55 push ebp
0001 8B EC mov ebp,esp
(...)
002D 5D pop ebp
So that must be the reason. Only that I don't know why, saving ebp on the
stack prevents an access violation from raising.
Mmmm... Help!

Tested on win98se and Win2k dmd 0.75 php-4.3.3 libs. If you want to compile the example I'll send you the OMF libs. Didn't posted to the ng because their +600k.

I really need small, reproducible examples of problems.
