attachInterrupt(11) clobbers previous attachInterrupt()

Starting with version 1.2.3 when I `attachInterrupt(11, cb11)` whatever interrup…t I registered in the previous attachInterrupt() call is not used and instead the interrupt for 11 is called. This is my minimum reproducing case. You'll need to wire 10 & 11 through buttons to ground. It prints `pin 11` for either button. ```cpp uint16_t lastPin = 0; void EICPin10() { lastPin = 10; } void EICPin11() { lastPin = 11; } void setup() { pinMode(10, INPUT_PULLUP); pinMode(11, INPUT_PULLUP); attachInterrupt(10, EICPin10, RISING); attachInterrupt(11, EICPin11, RISING); } void loop() { if (Serial && lastPin) { Serial.print("pin "); Serial.println(lastPin); lastPin = 0; } } ``` I did not see this behavior in 1.2.2. (My workaround is to downgrade to that version.)

It seems to be fixed by Adafruit but not yet integrated into PIO Sam
Thanks in advance
