Hello we have a labview Vi which tries to call a C function from a C/C++ dll. the function sets the python script paths and then calls Py_initialize.
Labview exits with no warning or error notification.
Windows error log shows the following.

The code to launch labview is as follows
/*Initializes the python script*/
DllExport
intStartPythonScript()
{
intindex =0;
Py_SetProgramName(
"PYTHON");
Py_SetPythonHome(s_py_path);
Py_Initialize();
if(s_py_path)
{
char* new_path= (char* )malloc(strlen(Py_GetPath())+1+strlen(s_py_path)+4);
memset(new_path,
'\0',strlen(Py_GetPath())+1+strlen(s_py_path)+4);
strcpy(new_path,Py_GetPath());
strcat(new_path,
";.;");
strcat(new_path,s_py_path);
PySys_SetPath(new_path);
printf(
"\r\n %s ",new_path);
free( new_path);
}
for(index =0;index<100;index++)
{
s_PyObjectInst[index] = NULL;
}
returnTRUE;
}
Would appriciate any help possible.
Regards
