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

[Luc De Wilde]

Dear Ivan,


Unfortunately the error did not go away, after the correction (delete[] where needed) still error free execution in R console but abort of the R process in Rstudio.

The debugger of RStudio did not give any useful information anymore. I then installed Drmingw and attached the R process of Rstudio to it.
When I then execute the tests everything happens error free ...
... until I close the debugger: then RStudio says that there is a fatal error in the R process and aborts it.

So of course I cannot find a cause this way!

Maybe you have an idea how to deal with this?

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://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fjrfonseca%2Fdrmingw&data=05%7C02%7CLuc.DeWilde%40UGent.be%7C74c6b594e5414ac8486c08dd03619cae%7Cd7811cdeecef496c8f91a1786241b99c%7C1%7C0%7C638670439969607386%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=hiUfEIBkezT%2FoWd%2FC5ZJncKFkTNUZPmqiavOCLOzOUM%3D&reserved=0<https://github.com/jrfonseca/drmingw>>.
