Just replying to a random mail of this mega-series. Bootstrap with Ada included was broken at random revisions throughout the last days which made testing any patch quite painful (well, as someone who includes Ada in bootstrap and testing by default). Can you please ensure that you don't break bootstrap all the time? I'm now simply testing patches w/o Ada for the time being (having wasted another hour for verifying it wasn't my patch causing the last bootstrap error I ran into, loads of +===========================GNAT BUG DETECTED==============================+ | 4.7.0 20110831 (experimental) [trunk revision 161655] (x86_64-unknown-linux-gnu) | | Storage_Error stack overflow or erroneous memory access | | Error detected at a-elchha.adb:41:25 | Thanks, Richard. > The following must compile quietly: > > gcc -c -gnat12 -gnata ml.ads > > with Ml_Type; > with Generic_Matrix; > package Ml is > > subtype T_Int32 is Ml_Type.T_Int32; > subtype T_Float32 is Ml_Type.T_Float32; > > package M32 is new Generic_Matrix(G_Float => T_Float32); > type T_Matrix32 is new M32.G_Matrix; > > subtype Range2 is T_Int32 range 0 .. 1; > subtype Range3 is T_Int32 range 0 .. 2; > end Ml; > --- > package Ml_Type is > type T_Int32 is range (-2 ** 31) ..
