#5434: <no location info> for shadowing warnings in TH-generated code
---------------------------------+------------------------------------------
Reporter: byorgey | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 7.2.1 | Keywords:
Testcase: | Blockedby:
Os: Unknown/Multiple | Blocking:
Architecture: Unknown/Multiple | Failure: Incorrect warning at
compile-time
---------------------------------+------------------------------------------
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.
