Summary: Mysterious crash in SDL backend

Initial Comment:
This is going to be one annoyingly vague bug report.
I'm filing it partly because I'd like to know if anyone
else has seen anything like it.

I was replaying parts of Loom CD, using an April 5 CVS
snapshot, and on two occasions it crashed for me.
Here's a stack trace from one of the occasions:

#0  Normal3x(unsigned char*, unsigned, unsigned char*,
unsigned char*, unsigned, int, int) (srcPtr=0x404aab88
"#", srcPitch=646, null=0x0,
    dstPtr=0xc91da <Address 0xc91da out of bounds>,
dstPitch=1920, width=34,
    height=25) at common/scaler.cpp:792
#1  0x0804dae5 in OSystem_SDL::update_screen()
(this=0x815d798)
    at backends/sdl/sdl.cpp:315
#2  0x080521ad in Scumm::mainRun() (this=0x816e960) at
scumm/scummvm.cpp:1662
#3  0x08052396 in Scumm::go() (this=0x816e960) at
scumm/scummvm.cpp:1732
#4  0x080ae56a in main (argc=2, argv=0xbffffbf4) at
common/main.cpp:219

The other one was very similar, except I was using a
different scaler at the time.
