Serial.write(0x00) fails to compile

Reproduce el fallo de compilación de Due con el ejemplo adjunto de Serial.write y, a continuación, lee cores/arduino/UARTClass.h y cores/arduino/Print.h, donde se muestran las sobrecargas de write en conflicto. Confirma que el literal 0x00 compila mientras se conserva el caso existente de variable, y verifica el resultado con la compilación de Arduino Due.

just stumbled across a weird behavior. If I send a 0x00 via Serial.write(), compiler fails with the below error. Values other than 0x00 are fine, and also sending a variable with value 0x00 (see attached demo)

Notes:

• This occurs for all Serials (0-3) on Arduino Due. Mega and Uno are ok
• I am running Linux x64 with IDE 1.8.10 and SAM package 1.6.12
• a fresh re-install of the SAM package via IDE did not help

Here the compiler output:
