#1531: _result can get bound to the wrong value in a breakpoint
------------------------+---------------------------------------------------
Reporter: mnislaih | Owner: [EMAIL PROTECTED]
Type: bug | Status: new
Priority: low | Milestone: 6.8
Component: GHCi | Version: 6.6.1
Severity: normal | Keywords:
Difficulty: Unknown | Os: Unknown
Testcase: result001 | Architecture: Unknown
------------------------+---------------------------------------------------
Using test result001 in the example below.
`:list` shows that the tick is wrapping `map id xs` (it is not appreciated
here, but the said subexpression is highlighted in ghci).
However `_result` seems to be bound to the value of `f xs`
{{{
*Main> :b 1 20
Breakpoint 1 activated at result001.hs:1:12-20
*Main> f "abc"
Stopped at result001.hs:1:12-20
_result :: Bool
xs :: [a]
... [result001.hs:1:12-20] *Main> :list
1 f xs = case map id xs of
2 [] -> True
... [result001.hs:1:12-20] *Main> :fo _result
*** Ignoring breakpoint
_result = False
}}}
