The assignment of a RESHAPE()d array does not trigger
a run-time error with bounds-checking turned on.

% gfortran -O0 -g -fbounds-check gfcbug39_bounds_check.f90 && ./a.out
 Assignments with correct shapes after RESHAPE...
 a(:,1) =   1.000000    
 b(:,1) =   1.000000       2.000000    
 ...and with wrong shape (should fail with bounds checking on)
 a(:,1) =   1.000000    
 b(:,1) =   1.000000       2.000000    
 Must have missed an array bound violation after RESHAPE...


See the attached sample program for details.

Cheers,
-ha
