On second thought, why does zfs_builder.img depend on the size of
loader.elf and not zfs_builder.elf?
Are you familiar with the Makefile code ("git blame" suggests you wrote
it)? Can you please have a look?
Maybe this use of "image_size" in that specific code is a mistake
$@)
Note how it needs image_size, which runs readelf on loader.elf, but doesn't
depend on loader.elf.
I'll prepare a patch but am not sure I can reproduce it...

If the answer is no, then my question would be if we could at least not
duplicate the linker scripts. Can't x86 and aarch have the same list of
exported functions? And if two libraries contain the same symbols, could we
somehow automatically copy symbols between them?
> On Tuesday, December
Can you please remind me why we need both OSV_LIBC_API and putting the
function name in 5 different files?
Isn't there a big risk that later when all this export stuff is less fresh
in our mind, we forget one of these 6 places and create a mess?

would require much more elaborate changes to Musl's
stdio, which I didn't want to do.
The code in this patch is a modified version of
musl_1.1.24/src/stdio/setvbuf.c.
Fixes #1180.

Rick, can you please test this patch if it fixes the problem you had with
reading the cdrom image?
For me, it fixed the assertion failure, but then I saw some other error
(about a missing file /usr-data) which I guess is expected, but I don't
know how to fully test.

Thanks!
I'll try to reproduce it and open an issue.

Looks good, but I have just one trivial comment below.

g more and then dropping
a part of it) but I'm not sure that it should - or why this only started to
happen recently - so I don't want to go in this direction unless we know
why.

I see only a couple of these cases. Why did you need to do those

Right. This strange file was added in commit

This patch appears to be corrupt - the line "int tests = 0, fails = 0;" is
missing at least a space - and neither "git am" nor "patch" want to accept
it.
I don't want to try to fix it without knowing what else I might be missing
- so can you please resend
; on different compiler
versions.
Fixes #1175
Fixes #1176 (but the test fails in a new place, I guess I need to fix
another problem).

I committed this because I assumed you know what you are doing, but I am
curious: Why did you remove
sched::timer_base::expire() from the list? Has this specific function
become more interesting because of recent changes?
