Hi there,
I think this is a matter of unproper garbage collection or something similar
but I need some guru advice: A properly coded function (in C++, some double*
serve as input, and a .txt or .csv file is the output but the function call
is like "void func_name(double *input, char *path)" so nothing is actually
returned) which does some calculations using some QuantLib objects somehow
changes its behaviour under /clr compiler option. This I need to be able to
use it via SWIG under C#. Calculations are done as supposed to, but upon C#
program termination an "unknown software exception" (0xc0020001) at
0x7c81eb33 pops up. I googled a bit and indications point to a too quick
(unmanaged) object disposal where the program terminates before the C++
object does. Does this sound familiar to one of you? Are there any hints to
prevent this?
Thanks in advance for any hints and best regards
