[R-pkg-devel] New package with C++ code causes R abort in RStudio, not in R console.

[Luc De Wilde]

At last, with checking of the program with address sanitizer in Visual Studio, I found an "off by 1 error" in my code. Now all tests pass without problems in Rstudio.

Thank you very much, Ivan, for helping me with this - new to me - issues!

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 <https://github.com/jrfonseca/drmingw>.
