Title:
  Builds with gcc -fsanitize=address crashing on startup

Status in gcc-defaults package in Ubuntu:
  New

Bug description:
  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 at ws1:~/work/sqlite/bld4/tst$ ./a.out
  hello world
