cuda-gdb crashes in demangler

I received the following error when starting cuda-gdb against our test suite:

You may reproduce the error by writing a small program using xtensor’s xt::allclose
function.

The cause is probably https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68159 which was fixed 3 years ago in gdb>=8 https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=245978

Just here to say that I’m getting the same issue after I did an update to my system. My issue is also with xtensor. Here’s my output. Were you able to work around this?
