New description:
See attached test case, which causes this warning to be printed when
THShadowSplice.hs is compiled with -Wall:
{{{
<no location info>:
Warning: This binding for `x' shadows the existing binding
bound at THShadowSplice.hs:7:3
}}}
There ought to be some location info. I have also seen warnings of the
form
{{{
<no location info>:
Warning: This binding for `x' shadows the existing binding
bound at <no location info>
}}}
although I have not yet been able to construct a small test case which
exhibits this behavior.
