Could memory be trashed if string "hello" is assigned during declaration?

I know memory could be trashed with this:

char *str1;

str1 = "hello";

... but could anyone confirm whether the following may also cause memory to be trashed or, is the following okay, as it's assigned during declaration?

char *str1 = "hello";

Thanks!

both cases may cause memory corruption since
the memory allocated for the string is allocated
on the program stack.
that means that when you will exit the function in
which it was allocated this memory is "free".

Ya, if you put this in a function and attempt to return it, it will lead to memory corruption because the activation record of the function will be deallocated and the memory location pointed to by str1 will now be free for allocation. I'd given an answer for a simple case, like when you have a small main program containing the entire code which was posted in the question.

Cheers :-)
