Hello all,
I am enjoying running LTRANS. Thank you very much. I am reporting a minor bug in LTRANS code just in case. Some subscripts of arrays take 0, which causes segmentation violation while executing LTRANS. This error occurs only when compiling with bounds check option (e.g., -CB in Intel Fortran). I think it is safer to correct this.
