Summary: Nan or segfaults in scripting when assigning int to
array
Product: RTT
Version: 1.10.1
Platform: All
OS/Version: All
Status: NEW
Severity: major
Priority: P3
Component: Real-Time Toolkit (RTT)

I had trouble using array in a state machine or a program.
This code :

var array myArray(10);
 
for (var int cpt = 0; cpt < 10; set cpt = cpt +1 )
{
    set myArray[cpt] = cpt;
}

can produce nan values, or even a segfault.

This code :

var array myArray(10);
 
for (var int cpt = 0; cpt < 10; set cpt = cpt +1 )
{
    set myArray[cpt] = 1.0*cpt;
}

seems to run well.

Segfault confirmed with this test case:

BOOST_AUTO_TEST_CASE(testProgramAssignArrayIndex)
{
    // see if assigning an array from an int works (bug #773)
    string prog = string("program x {\n")
        + "var array myArray(10);\n"
        + "for (var int cpt = 0; cpt < 10; set cpt = cpt +1 )\n"
        + "{\n"
        + "   set myArray[cpt] = cpt;\n"
        + "}\n"
        + "for (set cpt = 0; cpt < 10; set cpt = cpt +1 )\n"
        + "{\n"
        + "   do test.assert( myArray[cpt] == cpt );\n"
        + "}\n"
        + "}\n";
    this->doProgram( prog, &gtc );
    this->finishProgram( &gtc, "x");
}
