r24294 does not initialize properly
« on: April 30, 2009, 08:17:18 am »
I'm getting a error in Q_strncpyz about a NULL dest.

Code: [Select]

...found font f_verysmall_bold (0)
...found font f_verysmall (1)

Re: r24294 does not initialize properly
« Reply #1 on: April 30, 2009, 12:39:05 pm »
Is MN_Init is called?

THats funny, we see again:
Code: [Select]
type = {
        op = 22 '\026',
        param1 = 6 '\006',
        param2 = 144 '?'
      },
      data = 0x1606902c,
      data2 = 0x40000,
But mn is clearly not initialized.
