I have also ran into this problem, in my case though I have managed to reduce the issue down to an fgets call when reading a pipe. The following code causes the issue for me if I try and debug it: #include #include int main(int argc, char** argv) { char out[100] = {0}; FILE *pipe;

Hi all, So I have a C dll written in MSVC which is being called by a Cygwin programmed compiled with gcc. So far it all works ok apart from when I try and pass an array that the dll should then change. For example I have this in the dll: __declspec(dllexport) void array_read_write(double *sr
