nostr:npub1wg02ev7lfmnrwsjqu2tcm2qm4gw65aw0dyywfwvgafqnqyf02wmqhht0yf I see 2 issues there:

- strdup is assumed to succeed (although allocating only 6 bytes is very likely to work).

- free()'ing a memory address that doesn't correspond to the address malloc()'d is undefined behavior.

Regardless, that really should be written as:

#include

int main()

{

puts("Hello"+1);

return 0;

}
