Sat 30 Apr 2016 07:08:50 AM UTC, comment #2: As all the upstream code is using large array source_f/ts_upo.f: parameter(nx=1000000,mper=20) real xp(mper),fvec(mper),xor(mper,nx) It seems the F77 code should be updated to F90 darray http://www.tutorialspoint.com/fortran/fortran_dynamic_arrays.htm	marco atzeri <matzeri>
Sat 23 Apr 2016 07:43:52 PM UTC, comment #1: 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.	Juan Pablo Carbajal <juanpi>
Fri 22 Apr 2016 02:34:57 PM UTC, original submission: Critical on 32bit cygwin https://www.cygwin.com/ml/cygwin/2016-04/msg00564.html 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". Ugh.	marco atzeri <matzeri>
