Calling Wire1.begin(); Crashes Mbed OS

Official Hardware Mega GIGA R1 WiFi
1

While trying to get an I2C device to work on pins 101 and 102 of a Giga R1 I ran into a problem using Wire1. Using the code below causes the board to crash. Both Wire and Wire2 do not appear to have this issue.

#include "Wire.h"
void setup() {
  // put your setup code here, to run once:
  Wire1.begin();
}

void loop() {
  // put your main code here, to run repeatedly:

}

EDIT:
Rolling back to Mbed OS version 4.0.10 this issue does not occur. Only seems to happen on version 4.1.1
