The fld pointer is valid. In the debugger, just before executing the
FldSetFont call, I look at the field object. All the elements appear to
be fine; in particular, the "font" element has the value "fontStd".
If I call FldSetFont with "fontStd" as the second argument, no warning
occurs. This is expected: a quick look at the FldSetFont source shows
that it returns immediately if the new font is the same as the present
font (i.e. there's nothing to do).
Here's another data point: if I define the field with insufficient
height to handle the font I want to use, I get a bus error right after
the "write to low memory" warning. E.g. if I define the field to be 11
pixels high, and I try to set the field to fontLarge (which is 15
pixels high).
