Comment #4 on issue 330 by [email protected]: Support re-exec of
sanitized executable with preloading libasan on Linux and Android
https://code.google.com/p/address-sanitizer/issues/detail?id=330
Why ban this case? Doesn't it work with LD_PRELOAD?
No, dlopen may be executed in the middle of a working program when some
files already got written so reexecution would change the semantics
unpredictably.
Can you please remind why GCC doesn't use the static runtime library?
Well, both GCC and Clang support both static and dynamic runtimes, it's
just the default choice in GCC is different (for historical reasons). One
good thing about AsanDSO is that it allows running sanitized .so with
unsanitized executables.
