Pardon me if I report a bug of an out of date version.

Mine is 2.0(2.7.2.1) (is that not getting pretty old?).

Assuming I've defined

type matrix = array[1..4] of array[1..4] of integer;

Then an error of mine like

matrix[1][1]:=1;

instead of

lorentz[1][1]:=1;

where lorentz is defined as a type matrix in the var field, will make GPC crash.

gpc: Internal compiler error: program gpc1 got fatal signal 6

F.P.L
