The reduced testcase is:
SUBROUTINE DGEBAL( JOB, N, ARRAY, LDA, ILO, IHI, SCALE, INFO )
CHARACTER JOB
DOUBLE PRECISION ARRAY( LDA, * ), SCALE( * )
LOGICAL NOCONV
140 CONTINUE
DO 200 I = K, L
C = DNRM2( L-K+1, ARRAY( K, I ), 1 )
R = DNRM2( L-K+1, ARRAY( I, K ), LDA )
ICA = IDAMAX( L, ARRAY( 1, I ), 1 )
CA = ABS( ARRAY( ICA, I ) )
IF( C.EQ.ZERO .OR. R.EQ.ZERO )
$ GO TO 200
IF( G.LT.R .OR. MAX( R, RA ).GE.SFMAX2 .OR.
$ MIN( F, C, G, CA ).LE.SFMIN2 )GO TO 190
F = F / SCLFAC
G = G / SCLFAC
190 CONTINUE
CALL DSCAL( N-K+1, G, ARRAY( I, K ), LDA )
200 CONTINUE
IF( NOCONV )
$ GO TO 140
END
The options to use to reproduce: -mcpu=power8 -O2 -fPIC
