As all the upstream code is using large array

  real xp(mper),fvec(mper),xor(mper,nx)

It seems the F77 code should be updated to F90 darray

Will look into this, it seems we just used the original code so it might be upstream. Howver chances of it getting fix there are slim, lets see what we can do on this side of the rope.

Critical on 32bit cygwin

4 of the tisean shared libs have loaded image > 10 time bigger
than octave itself.

Size       Shared lib
0x01038000 /usr/bin/cygoctinterp-3.dll
0x0104f000 /usr/bin/cygoctave-3.dll

0x0cb25000 /usr/lib/.../__surrogates__.oct
0x0cb25000 /usr/lib/.../__upo__.oct
0x0cb25000 /usr/lib/.../lazy.oct
0x0cb26000 /usr/lib/.../__c1__.oct

As noted by another maintainer

Static Data : The bss segment is taking up much space...
The F77 parts apparently use COMMON arrays "the sizes are chosen
generously for normal purposes".
