[squeak-dev] Re: [Pharo-project] [BUG]LargePositiveInteger(Object)>>error:Eliot Miranda eliot.miranda at gmail.comWed Jan 12 23:52:05 UTC 2011
Hi All,
I think I've found the reproducible case for the MessageNotUnderstood:
LargePositiveInteger>>pixelValueForDepth: bug in the
StackToRegisterMappingCogit. The symptom may be that the register
arguments get shuffled incorrectly through an inline send miss. Here's an
example that produces an MNU every time:
| s a ca |
s := #(1 -1).
a := Array new: 2.
ca := ColorArray new: 2.
a replaceFrom: 1 to: 2 with: s.
ca replaceFrom: 1 to: 2 with: s.
I'll try and look at this this evening.
best
Eliot
