// Test the behaviour of the JNI "char" releasing functions, under Xcheck:jni,
// when they are passed "char" arrays obtained from different sources:
// - source_mode indicates which array to use
//   - 0: use a raw malloc'd array
//   - 1: use an array from GetCharArrayElements
//   - 2: use an array from GetStringChars
//   - 3: use an array from GetStringUTFChars
//   - 4: use an array from GetPrimitiveArrayCritical
// - release_mode indicates which releasing function to use
//   - 0: ReleaseCharArrayElements
//   - 1: ReleaseStringChars
//   - 2: ReleaseStringUTFChars
//   - 3: ReleasePrimitiveArrayCritical
