Thanks to your instructions I have found the probable reason of the crash:
char* items allocated with "new char[...]" were deleted with 'delete' and not
with 'delete[]' in one of the destructors. I will recheck my code and retry all
tests.
For your information: Visual Studio debugger works with the debug info stored
in the dll, it asks for the location of the source file (.cpp) and then shows
the correct location of the problematic instruction.
Thanks a lot!
Luc

So the crash does happen inside lavaanC.dll, did I get this right?
If you set the environment variable DEBUG to a non-empty string before
compiling the package, the resulting *.dll will have debug information
in the DWARF format (this is set in file.path(R.home('etc'), 'x64',
'Makeconf')). Visual Studio might not work with it, so you could
install gdb into Rtools using pacman, or you could try to give the
executable to Dr. Mingw
