Two points in respect to PR#2867.
First, the trivial one:
(1) In Lapack.c, on lines 806 and 812, there are calls of
F77_CALL(dgeqp3). But the error messages on lines on lines 809 and 815
refer to "dqeqp3", i.e., they currently have a "q" where
they should have
a "g".
Secondly, the non-trivial one
(2) I have built R-1.7.1 under Solaris 7 on a SunUltrasparc 2 using
gcc-2.95.3. On running make check-all, bug #2867 still rears its head.
Here is the tail of the output from reg-tests-1.Rout.fail

Error in qr(X, LAPACK = TRUE) : error code -14983444 from Lapack routine
dqeqp3
Execution halted
As an R novice, I am puzzled that the call to dgeqp3 has more arguments
than dgeqp3 itself. The call has an extra argument "rwork". But this
could explain the strange error code!
The call:
F77_CALL(dgeqp3)(&m, &n, REAL(A), &m, INTEGER(jpvt), REAL(tau),
&tmp, &lwork, rwork, &info);
The subroutine:
SUBROUTINE DGEQP3( M, N, A, LDA, JPVT, TAU, WORK, LWORK, INFO )
Thanks for R!
