heh. Probably introduced by
commit 4edcf1caa52a09fffaf032a35ffd129259084096
Author: Alexandre Julliard <julliard at winehq.org>

gdi32: Make gdi.exe into a stand-alone 16-bit module.
In libs/wine/loader.c, wine_dll_get_owner opens the directory
dlls/gdi.exe16 and tries to read from it; read returns -1,
buffer is nul-terminated at offset -1 (a write underflow on a stack-allocated
buffer) and hilarity ensues.
