Btw, if I don't use writeln it doesn't fail..
I think you have a bug at line 42.
On a serious note, it might have helped if you'd attached source code,
or at least binaries.
Hmmm.. Seems my post last night didn't get through..
Here's the code and necessary libraries: http://share1t.com/4xgt2l
What appears to be an error here is in fact an Access Violation at
mysql_close.
Here is a reduced test-case:
import mysql;
void main()
{
auto res = mysql_library_init(0, null, null);
auto cn = mysql_init(null);
mysql_close(cn);
}
Then I decided to check whether it is D's fault or not by porting this
short program to C. Here is what I got:
// mysql.c
int mysql_server_init(int argc, char **argv, char **groups);
struct MYSQL* mysql_init(struct MYSQL*);
void mysql_close(struct MYSQL*);
#define mysql_library_init mysql_server_init
#define NULL 0
#include <stdio.h>
int main()
{
int res = mysql_library_init(0, NULL, NULL);
struct MYSQL* cn = mysql_init(NULL);
printf("here");
mysql_close(cn);
return 0;
}
This program works fine, BUT try commenting out the "printf" call and it
crashes, too. That said, it is unlikely to be DMD fault here. Are you sure
those prototypes and/or .lib/.dll files are fine?
