While "71" is not a standard documented error code for xclm.exe , users often encounter licensing or performance hurdles: Licenses - MPLAB® XC Compilers - Microchip Technology
The appearance of "Xc8 71" alongside xclm.exe in system logs or community development forums usually signals one of three technical events:
(XC License Manager) is a command-line tool used by Microchip Technology to activate, manage, and verify license keys for the C Compiler. Xclm.exe Xc8 71
Before this update, developers using the compiler noticed that "debug optimization" settings weren't behaving the same way across different microchip families. This inconsistency made it hard to trust that code would debug correctly if you switched chips.

This will help me better understand your issue and provide more tailored guidance.
When you install the MPLAB XC8 compiler for 8-bit PIC or AVR microcontrollers, (and its background service, RLM) is installed to handle both workstation and network licenses. : The path to the license manager or
The acts as the gatekeeper between your C source code and the highly advanced optimization modes of the compiler. When you initiate a project build inside Microchip MPLAB X IDE, the compiler driver invokes xclm.exe to check the system’s licensing state.
If a user is dealing with an older "71" related update, it often means ensuring the Xclm.exe utility is updated to the latest version compatible with the installed compiler to prevent activation failures. 3. Common Scenarios for Xclm.exe and XC8
