[Gambas-user] Illegal instruction when calling a C library

[martin p cristia]

After compiling and installing 3.8.3 (from 3.8.2):

this call...

   modLibMatrix8.setCG(cgx, cgy, cgz)

declared as...

   Public Extern setCG(x As Float, y As Float, z As Float)

(no modifications in the C  .so library, or in the gambas code)

void setCG(double x, double y, double z)
{
// saving CG location for future use
cg.x = x;
cg.y = y;
cg.z = z;
}

gives

   "Illegal instruction"
