Every program starts in __libc_start_main, so this would suppress
everything. This doesn't happen in practice because asan by default
is unable to unwind the stack. Setting
ASAN_OPTIONS=fast_unwind_on_malloc=0,malloc_context_size=15 can unwind
the stack, and if malloc_context_size is large enough it will indeed
suppress everything.
