I use the c++ standard regex library in ESP32. When i use this code i get error message. Why?

#include <regex>

using namespace std;

void setup() {
  Serial.begin(115200);
  delay(5000);
  char str[] = "false;true;false;true;false;true;true;14;59";
  if(regex_search(str,regex("^((false;|true;){7}(([0-1][0-9])|([2][0-3]));(([0-5][0-9])|([0][0])))$")))
  Serial.println("match");
  else
  Serial.println("not match");
  
}

void loop() {
  // put your main code here, to run repeatedly:

}

The error message:

assertion "heap != NULL && "free() target pointer is outside heap areas"" failed: file "/home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/heap/heap_caps.c", line 267, function: heap_caps_free

I think this says you are supposed to pass a std::string as the first argument and a std::smatch as the second argument.

  string str = "false;true;false;true;false;true;true;14;59";
  smatch match;
  if (regex_search(str, match, regex("^((false;|true;){7}(([0-1][0-9])|([2][0-3]));(([0-5][0-9])|([0][0])))$")))
    Serial.println("match");
  else
    Serial.println("not match");
