IDE Crash on Failed Compile

[martindiv]

Describe the problem

IDE crashes and restarts on failed compile.

To reproduce

1. Add the following URL to the "Additional Boards Manager URLs" preference:

   https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json
   

2. Use Boards Manager to install the "M5Stack" boards platform.
3. Select Tools > Board > M5Stack > M5Cardputer from the Arduino IDE menus.
4. Select Tools > Board > Core Debug Level > Debug from the Arduino IDE menus.
5. Create a sketch with the following code:

   #include <M5Cardputer.h>
   #include <esp_log.h>
   
   i2c_port_t portAnum = M5.Ex_I2C.getPort();
   int8_t portASDA = M5.Ex_I2C.getSDA();
   int8_t portASCL = M5.Ex_I2C.getSCL();
   
   M5GFX display;
   
   void setup() {
     Serial.begin(115200);
     auto cfg = M5.config();
     M5Cardputer.begin(cfg, true);
     display = M5Cardputer.Display;
   
     display.clear(BLACK);
     display.setTextSize(2);
     display.setTextColor(GREEN,BLACK);
     display.drawCenterString("I2C Port Info",120,0);
     display.setCursor(0,20);
     display.printf("Port Number: %d\n"(int)portAnum);
     display.printf("SDA Pin: %d\n",portASDA);
     display.printf("SCL Pin: %d\n",portASCL);
     Serial.println("SDA Port Information");
     Serial.printf("Port Number: %d\n"(int)portAnum);
     Serial.printf("SDA Pin: %d\n",portASDA);
     Serial.printf("SCL Pin: %d\n",portASCL);
     Serial.println("-------- END -------");
   }
   
   void loop() {
     // put your main code here, to run repeatedly:
   }

   Note: syntax errors are intentional. This time :)
6. Use Library Manager to install the "M5Cardputer" and "M5GFX" libraries.
7. Select Sketch > Verify/Compile from the Arduino IDE menus.

🐛 Compile will fail and the IDE just waits at "Compiling Sketch" for some time then crashes and restarts.

Expected behavior

No crash or ping timeouts on failed compile.

Arduino IDE version

20250406 (nightly build)

Operating system

Linux

Operating system version

Linux Mint latest

Additional context

When I perform the procedure provided in the "To reproduce" section of the report, I get the following results:

• When using Arduino IDE 2.3.4: Doesn't crash, but takes a really long time to figure out the compile failed. Sometimes gives a "Ping timeout" error.
  • Terminal logs: arduino-ide_2.3.4_Linux_64bit-crashlog-nocrash.txt
• When using Arduino IDE 2.3.5: Doesn't always crash but still crashes more than it doesn't.
  • Terminal logs: arduino-ide_2.3.5_Linux_64bit-crashlog.txt
• When using 20250406 nightly build: So far 100% crashes on failed compiles.
  • Terminal logs: arduino-ide_nightly-20250406_Linux_64bit-crashlog.txt

The section of the 2.3.5 logs that looks interesting is:

The 2.3.4 logs do not contain any content like this (other than the "Adding libraries dir" line, which I included for context).

The nightly build logs contain content similar to the 2.3.5, logs, but they contain 68 instances of the "transport error" exception, while the 2.3.5 logs only contain a single instance of the exception.

[... and 66 more instances of the exception]

The fault still occurs after I deleted the ~/.arduino15 and ~/.arduinoIDE folders and then reinstalled the "M5Stack" boards platform.

Almost forgot:
Things I've already tried:
Remove ~/.arduino15 and ~/.arduinoIDE and re-setup. Did this for 2.3.5 but none of the others.
Go into the settings ui, make a minor change and change it back. (to force a rewrite of the settings file(s).)

All three debug logs are from the same ~/.arduino15 and ~/.arduinoIDE.
