Yes, this is a font bug.

The source engine uses fonts to render the names and weapon symbols. It creates
a d3d surface for them and uses GetGlyphOutline to read the font symbol into
that surface.

Unfortunately the surface has a fixed size, and if GetGlyphOutline returns a
bigger glyph than hl2 expects, it causes an overflow on the stack and the
return address or a class instance pointer that is safed on the stack gets
overwritten, and the game crashes a few instructions later.

This is essentially a hl2 bug, because it should honor the size returned by
ggo, rather than finding it's own or hardcoding it. Beyond that, I am not sure
if Wine or freetype is to be blamed for rendering the font differently, but if
it is freetype, then we have a problem. Freetype doesn't aim for bug-for-bug
compatiblity with windows as far as I know.
