sysinfo 0.1.0a - vdr

1 Jun 2009


      Hi,
I am trying to get this plugin working with vdr 1.7.7.  When I bring it
up from the menu it segmentation faults.  The relevant sections from the
backtrace are :
#0  0x00000000004a4b2d in cBitmap::DrawText (this=0x2acb4e0, x=10, y=3, 
    s=0x7fdb8302fb90 "SysInfo 0.1.0a", ColorFg=4278190080,
ColorBg=2164260863, 
    Font=0x754040, Width=0, Height=0, Alignment=5) at osd.c:454
454	     int w = Font->Width(s);
And the full thread bt is

to me this looks like the Font passed into DrawText is invalid.  This is
set up in sysinfoosd.h thus:
static const cFont *font = cFont::GetFont(fontOsd);
Is there something obvious here that someone with more experience of the
code can spot?
Thanks,
Scott
