Re: Segmentation fault (core dumped)

You must help with more information:

==================================
Try some different approaches. Isolate the following,
as a separate script. run it

    diru = "/home/Vishali/Documents/dadosVentos/Speed/"
    filu = systemfunc("cd "+diru+" ; ls wind*nc")
    nfilu = dimsizes(filu)

    print(nfilu)
    print(filu)

================================
Another separate script:

    yrStrt = 1998
    yrLast = 2004
    nyrs = yrLast-yrStrt+1
    klev = 17
    nlat = 73
    mlon = 144
    ntim = 12*nyrs ; number of months

    wMon = new ( (/ntim,klev,nlat,mlon/), "float", 1e20)
    tMon = new ( ntim, "double", "No_FillValue")

    print("success")
==============================

Also, pick out (say) the 1st file and use ncl_filedump

%> ncl_filedump wind...nc
