Without knowing that C code, we cannot know. Have you read Writing R
Extensions carefully? I.e. take care with memory allocation and printing
as mentioned in the manual.

Hello,
I wrote a function in C, which works fine if called from the
main-function in C.
But as soon as I try to call this function from R like .C('foo',
as.double(x), as.integer(y)), the programm crashes.
I created a dll with the cmd command R --arch x64 CMD SHLIB foo.c and
loaded it into R with dyn.load().
What can be the cause of such behaviour?
Again, the C-funcion itself works, but not if called from R.
Thanks
Grigory Alexandrovich
