Not sure if this is an actual syntax error. The SRC/sgeqp3rk.f file has the following:

*           Factorize JB columns among the columns A(J:N).
*
           CALL SLAQP3RK( M, N_SUB, NRHS, IOFFSET, JB, ABSTOL,
    $                     RELTOL, KP1, MAXC2NRM, A( 1, J ), LDA,
    $                     DONE, JBF, MAXC2NRMK, RELMAXC2NRMK,
    $                     JPIV( J ), TAU( J ),
    $                     WORK( J ), WORK( N+J ),
    $                     WORK( 2*N+1 ), WORK( 2*N+JB+1 ),
    $                     N+NRHS-J+1, IWORK, IINFO )
*
*           Set INFO on the first occurence of Inf.
*

After reaching 19%, it seems to hang forever.
