Crash attempting to draw monichrome bitmat to EPD

[ScottCUSA]

• Arduino board: Adafruit MagTag (black silkscreen)

• Arduino IDE version (found in Arduino -> About Arduino menu): 2.2.3

• List the steps to reproduce the problem below (if possible attach a sketch or copy the sketch code in too): LIST REPRO STEPS BELOW

The MagTag seems to crash and reboot attempting to draw the attached monochrome bitmap weather_bg.bmp (slightly modifed version from WeatherStation circuit python example) using Adafruit_ImageReader_EPD on an MagTag.

Displaying the blinka.bmp works fine, and loading the weather_bg.bmp to an Adafruit_Image_EPD works fine, but attempting to draw it onto the display caused the MagTag to hard reset.

A added some Serial prints to the coreBMP function, as an attempt to figure out what's wrong. It seems to get past the end of the scan line for loop, but it doesn't seem get to the end of the coreBMP function. I haven't been able to figure out why.

I've attached the weather_bg.bmp and the ino I'm using, it's just a trimmed down version of the ThinkInkDisplays example from this repo.

Serial Output:

I was able to connect to the UART, and this was output repeatedly:
