ASan init calls itself (but only when not running under a debugger)

Anyone have any suggestions for how to debug an ASAN init failure on Windows (hitting the “ASan init calls itself!” assert)? Something as simple as hello world is failing. What’s particularly interesting is that if I run the program under windbg, it works as expected (after doing an ‘sxi av’ to let the intentional AVs pass through, and stepping over a couple of interception failure breakpoints), so I have no idea how to figure out what’s going on if I can’t observe the issue under a debugger.

It seems to be something to do with how the executable is being built, since if I take the generated binary and run it on a different machine I experience the same issue. But if I perform the same steps to build the code on another machine it’s working there… The inverse is also true in that I can take a binary generated on the working machine and run it on the non-working machine and it success there (without needing the debugger).

I’ve tried various tweaks to compiler/linker flags, SDK versions, etc. over the last couple of days to no avail. I’ve also tried disassembling and comparing the working vs broken binary in a disassembler but without the ability to observe the issue under a debugger and compare an execution trace I’m basically fumbling around in the dark.

One more note of interest is that it appears to work if I dynamically link the CRT (/MD), but I need to statically link the CRT in order to use libFuzzer per the documentation, so that’s not going to work as a solution for me since I’m specifically trying to build a fuzzer.

Any help would be greatly appreciated since this is blocking my ability to use ASAN (and by extension libFuzzer) on Windows.

Thanks for your time. Demonstration of the issue is shown below (note that when run under cdb you can see the “Hello world” printed, and there are no ASAN asserts raised):
