Minimal Reproductible Example (MRE)

Anything using the following seems to cause the problem.
Removing all references to the ESPAsyncWebServer from the codebase and removing the dependencies eliminates the build failure.

        [env:esp32-c3]
        platform = espressif32
        board = esp32-c3-devkitm-1
        framework = arduino
        board_build.mcu = esp32c3
        board_build.f_cpu = 160000000L
        build_flags = 
            -DASYNCWEBSERVER_REGEX
            -D ARDUINO_USB_MODE=1
            -D ARDUINO_USB_CDC_ON_BOOT=1 
            !echo '#define GIT_SHA1_VERSION "'$(git log |head -1 |cut -c8-)'"' >> src/version.h
        lib_deps = 
            https://github.com/ttlappalainen/NMEA2000.git
            https://github.com/ttlappalainen/NMEA0183.git
            https://github.com/ieb/NMEA2000_twai.git#platformIOUse
            ESP32Async/AsyncTCP
            ESP32Async/ESPAsyncWebServer
            paulstoffregen/Time@^1.6.1
            ModbusClient=https://github.com/eModbus/eModbus.git

I confirm that:

• I have read the documentation.
• I have searched for similar discussions.
• I have searched for similar issues.
• I have looked at the examples.
• I have upgraded to the lasted version of ESPAsyncWebServer (and AsyncTCP for ESP32).

Please dont do anything yet. I am double checking its not me.

We do build on C3 and build pass: https://github.com/ESP32Async/ESPAsyncWebServer/actions/runs/13674993269/job/38233414420

that is not an issue - will convert it to support discussion.
