#3883: --show-iface hangs on certain .hi files
---------------------------------+------------------------------------------

Type: bug | Status: new

---------------------------------+------------------------------------------
In a GHC build, try
{{{
inplace/bin/ghc-stage2 --show-iface array/dist-
install/build/Data/Array/Base.hi
}}}
This hangs for me, right after
{{{
b0318967c2f8fdf2005760546e36e780
$fIArrayUArrayBool_$cunsafeAccum :: forall i e'.
GHC.Arr.Ix i =>
(GHC.Bool.Bool -> e' ->
GHC.Bool.Bool)
-> Data.Array.Base.UArray i
GHC.Bool.Bool
-> [(GHC.Types.Int, e')]
-> Data.Array.Base.UArray i
GHC.Bool.Bool
{- Arity: 4, HasNoCafRefs, Strictness: ALU(LLLL)L,
Inline: INLINE{3},^C
}}}
and the GHC process is uninteruptible, which suggests it has gone into an
infinite non-allocating loop.
Appears to be HEAD only.
