Some observations:

1. the problem does not occur when running gpc directly rather than  
with make, even when passing the same compiler switches (this sounds  
like random behaviour and makes me think there is an uninitialized  
variable somewhere in the compiler source code)

2. the problems disappears when I remove Turbo3 from the USES clause  
in aturbo3test.pas

3. the problem persists when I reduce the Turbo3 unit to nothing but

import

        System (MemAvail => System_MemAvail,
                MaxAvail => System_MaxAvail);

Will try to further narrow this down in units/System.pas.
