ESP8266 problem

[MagicHardware]

Hello,
I try your library, is awsome, but I have trouble to run it on ESP8266 (D1 mini V2). I use PlatformIO. When I comment or change second LOG to PRINT it work with no error. I am confused. This code do exception (on ESP32 it work with no problem).
main.cpp:

#include <DebugLog.h>

void setup() {
    Serial.begin(115200);
    delay(2000);
    LOG_SET_LEVEL(DebugLogLevel::LVL_TRACE);
    LOG_DEBUG("Program start");
}

void loop() {
    LOG_ERROR("Main");
}

Exception:

Exception (3):
epc1=0x4000bf64 epc2=0x00000000 epc3=0x00000000 excvaddr=0x4023b017 depc=0x00000000

I check with ESP-01 (ESP8266) . Exception is the same.
