With the 9.0 version of libasan I also experience an additional crash which is
100% reproducible:

The crash is not 100% reproducible. Looks like it is a race.
I'll check whether I can give you access to a system on our side.

Looking at the backtrace, the effects are very different between gcc 7.4 and
9.0. Making it work on a different glibc wouldn't help for me. CentOs 7.5 ==

I canse it plays a role:
I am running on a CentOS Linux release 7.5.1804
which has kernel version 3.10.0-862.11.6.el7.x86_64

ASAN from git crashes like this. Looks like a double fault.

Unfortunately my application is huge and spawns many threads.
Can you propose some debugging aid. I am building gcc myself, so I can add
anything to libasan that you want.

Works after applying the patch in my non-reduced test case, too.

The ICE only occurs on -O2 and up, -O1 works.

I can say that it works with gcc 4.8.
Clang 3.7 could take a while because I suffer from an incompatibility between
gcc and clang so I cannot bind my C++ libs compiled with gcc to a

I get the point.
However, I could imagine that it is a quite common scenario to have a binary
