Ok.

Ok.
Interesting, I run the same code bla.adb on a Unix machine. The first part of the second column (that one which writes ffbec...), and it does not appear here. So the lines look like
00000000 00000001 D ada__exceptions_E
However when I add all the column, the result also seems incoherent, around 8GB. The real bla.out generated is ~478kB.
