It's reducing with the stricter test, expect something in around 24 hours.

btw, I also noticed these warnings:

Aha, I'll validate against g++ -O0.

Unfortunately, clang doesn't accept the preprocessed source, only the original.

Sure, I'll redo the reduction.

In current master (90c3a62272313bb08cd5d9a948ff2d71af73b294), we don't ICE, but
instead get this error:
coroutine-initializer-list.cc: In member function ‘task task::e()’:

It's still >7MB long, so I'll stop reducing.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101420
--- Comment #16 from Avi Kivity ---
So I confirm it's a dup. Are you still interested in a reduced testcase?
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101420
--- Comment #15 from Avi Kivity ---
If I move the sub-expression that contains the std::initializer_list outside
co_await, the internal error is avoided.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101420
--- Comment #14 from Avi Kivity ---
Very likely it's a dup:
db::view::view_update_builder builder = co_await
db::view::make_view_update_builder(
base,
std::move(views),

Ugh, I forgot g++ isn't the compiler proper and setting a breakpoint is going
to be tricky.

How does one ask gcc to generate a backtrace on ICE?

Still bad on trunk. Clang gets this right:

I do not have a patch, and unfortunately, it will take me several months at the
most optimistic least to get up to speed with gcc internals to fix this. I've
switched to clang, but I'd really like to switch

A reminder that coroutines are crippled without this fixed, as it is standard
practice these days to use sanitizers.

No pressing reason to backport (for me gcc coroutines are useless anyway due to
