call_once and TSan
Hi,
I'm trying to write a TSan interceptor for the C++11 call_once function. There are currently false positive reports, because the inner __call_once function is located in the (non-instrumented) libcxx library, and on macOS we can't expect the users to build their own instrumented libcxx.
TSan already supports pthread_once and dispatch_once by having interceptors that re-implement the

Allow reopening on Phabricator
If you can find out whether it's possible with the latest phab, I can
update our instance.

greendragon build noisy due to mmap_stress.cc

I unfortunately just got another failure, so this is clearly not darwin
only or even low-noise on none-darwin platforms:

I very much appreciate that people are investigating this issue...

[LLVMdev] Proposal: ASan debugging API
Hi,
I would like to improve the debugging experience for ASan. The idea is to
have a couple of useful commands in LLDB (probably implemented as Python
scripts) that could help the user when they are debugging an ASan-enabled
binary. We already have some debugging API (asan_interface.h):
// Print the description of addr (useful when debugging in gdb).
void __asan_describe_address(void

greendragon build noisy due to mmap_stress.cc
Hm, I tried to reproduce this as well, but unsuccessfully. From the crash report: EXC_I386_GPFLT means we’re dereferencing a non-canonical pointer, in this case “0x00486000000025df”. This happens at wrap_OSSpinLockLock+17, which is just after the prologue and just after calling cur_thread(). So I’d say it happens when we’re dereferencing the pointer returned by cur_thread(). On OS X, we’re
