This sketch causes the Web Editor to crash (is it my fault or a bug?)

I don't know why this R&D sketch I made from example code causes the Web Editor to crash but it does. The sketch has two files. This is the main file:

#include <SPI.h>
#include <MPU6050.h>
#include <Wire.h>
#include <U8g2lib.h>
#include "lib_test.c"

MPU6050 mpu;

int16_t ax, ay, az, gx, gy, gz;

U8G2_SSD1306_128X32_UNIVISION_F_HW_I2C u8g2(U8G2_R0);

const int buttonPin = 4;

int counter = 0;
int buttonState;        
int lastButtonState = LOW;   

unsigned long lastDebounceTime = 0;  
unsigned long debounceDelay = 50;    

void setup() {
  pinMode(buttonPin, INPUT);
  u8g2.begin();
  Serial.begin(9600);
  mpu.initialize();
  if (!mpu.testConnection()) {
    while (1);
  }
}

void loop() {
  mpu.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);

  int reading = digitalRead(buttonPin);
  
  if (reading != lastButtonState) {
    // reset the debouncing timer
    lastDebounceTime = millis();
  }

  if ((millis() - lastDebounceTime) > debounceDelay) {

    if (reading != buttonState) {
      buttonState = reading;

      if (buttonState == LOW && counter >= 0 && counter < 10) {
        counter++;
      }
      else if (buttonState == LOW && counter >= 2) {
        counter = 0;
      }
    }
  }

  lastButtonState = reading;

  switch (counter) {
    case 1:
      printInt(10, 10, counter);
      break;
    case 2:
      printInt(10, 10, ax);
      break;
    default:
      printInt(10, 10, 0);
      break;
  }
}

This is the second file, which contains the printInt() function:

#include <U8g2lib.h>

void printInt(int _cursorX, int _cursorY, int _varToPass) {
  u8g2.clearBuffer();					
  u8g2.setFont(u8g2_font_t0_11_tf);
  u8g2.setCursor(_cursorX, _cursorY);
  u8g2.print(_varToPass);	
  u8g2.sendBuffer();					
}

The crash happened upon creation of the function file and seems to be caused by the #include up top. Except that it doesn't work if I remove it.

Is this a problem with me or the Web IDE?

EDIT - The name of the second file is "lib_test.c".

Just rename lib_test.c "lib_test.ino" and remove the #include from the first file. It will all compile together just fine. You don't need the #include in the new lib_test.ino file either

It worked. Thanks!
