[Solved] Leetcode Error: AddressSanitizer: SEGV on unknown address 0x55eb765425b8 (pc 0x55eb76542b86 bp 0x7ffd1bd2

Hi, I’ve come back to the article ᕕ (ᐛ) ᕗ
recently, I’m brushing leetcode, and there’s an error report about stack

 AddressSanitizer:DEADLYSIGNAL
=================================================================
==42==ERROR: AddressSanitizer: SEGV on unknown address 0x55eb765425b8 (pc 0x55eb76542b86 bp 0x7ffd1bd27d50 sp 0x7ffd1bd27d00 T0)
==42==The signal is caused by a WRITE memory access.
    #2 0x7fe2bd0fe0b2 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x270b2)
AddressSanitizer can not provide additional info.
==42==ABORTING

My code is as follows



bool isValid(char * s){
    bool answer;
    int i=0;
    char tem;
    stack S=creatstack;  //Something is wrong here, it should be a function but I forgot to add the brackets
    while(s[i]!='\0'){
        if(s[i]=='('||s[i]=='['||s[i]=='{') push(s[i],S);
        else{
            tem=pop(S);
            if((tem=='('&&s[i]==')')||(tem=='['&&s[i]==']')||(tem=='{'&&s[i]=='}')) ;
            else return false;
        }
        i++;
    }
    return true;
}

Change to

stack S=creatstack();

After that, the problem was solved
