    Bash -c and aliases don't mix.

    The problem is that the lexer terminates the string given to -c
with \377 (really (char)EOF).  The alias expansion code does not
consider \377 to be whitespace.  If you say "bash -c foo" when foo is
aliased, bash checks to see if foo\377 is aliased to anything.  It
isn't.
