Builds with gcc -fsanitize=address crashing on startup

[Dan]

Builds of any code using -fsanitize=address sometimes crash, as shown below. Sometimes they run successfully, sometimes failing with this "AddressSantizer:DEADLYSIGNAL" message. I've just run "software updater" and upgraded everything.

$ cat p.c

#include <stdio.h>

int main(int argc, char **argv){
  printf("hello world\n");
  return 0;
}
dan@ws1:~/work/sqlite/bld4/tst$ gcc -fsanitize=address ./p.c
dan@ws1:~/work/sqlite/bld4/tst$ ./a.out
hello world
dan@ws1:~/work/sqlite/bld4/tst$ ./a.out
hello world
dan@ws1:~/work/sqlite/bld4/tst$ ./a.out

Also affects me, using Uname: Linux 6.5.0-26-generic x86_64

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

The workaround mentioned here https://github.com/google/sanitizers/issues/1716

  sudo sysctl vm.mmap_rnd_bits=28

made the problem go away for me.
