I'm basing this suggestion on two things. One, that if you follow it, the code compiles: and two, that the diagnostic help you get when you try to use a in the repeat position suggests something very similar, see "other cases." It would require the compiler to know that a value that is attempted to be repeated is able though, which I don't know whether it can, but I figured I'd suggest this, and you can reject it if it isn't possible to do. Alternatively, the help text could say something like "if the value can be made , consider creating [...]" I was inspired to make this issue based on the output you get when you try to use a as an array initializer. For instance, the code produces the output No response
hey why im getting this error message all over my github repository ! whenever i commit some changes, The first changes i able to create pull request but after some other changes im not able to do that why im getting these error ! Please help

Bisected to but it probably just bubbles up a pre-existing issue that the OP could be massaged to emit without this PR, cc author just in case.
This worked fine before 1.70.0 so it's a regression.

I'm also seeing this on x86_64 with the recent nightlies: Update 1: It seems like in both cases it's related to cross. The original PR mentions problems with old versions. Could it be that cross needs to update their docker images? (Though they seem to be based on Ubuntu 20, which doesn't seem THAT old) Update 2: cross runs
Centos 7 used by i686-dist builder seems to use Binutils 2.27, dist-armv7 uses Binutils 2.32 and dist-various1 (so thumbv6m-none-eabi) uses Binutils 2.38. They all are indeed newer than:
hashbrown ci uses cross 0.2.5, which is the latest stable release for cross. To fix this issue with cross specifically, one can set the image used by cross to be a newer version, cross 0.2.5 images use ubuntu 16.04, we can change that with the env vars or config (see ) (make sure to set the correct env-var and image for the specific target)
The diagnostic looks similar to a binutils 2.41 change I made to fix ld: Allow RX8664GOTPCREL for call *_tlsgetaddr Threadlocal int a; int main() { return a; } % gcc -fno-plt -fpic a.c -fuse-ld=bfd -Wa,-mrelax-relocations=no /tmp/ccSSBgrg.o: TLS transition from RX8664TLSGD to RX8664_GOTTPOFF against .text' failed failed to set dynamic section sizes: bad value collect2: error: ld returned 1 exit status There is incompatibility between  and with GNU ld<2.41. You may need to figure out where similar semantics are used.
Ran into this in github CI today as well (e.g. ). Works fine locally on Arch though when I try to recreate it. EDIT: Managed to reproduce it locally. I was mixing up -gnu and -musl targets, my bad.

This is really not a great solution for projects that build binaries for releases though (like I do). To target an old enough glibc to work on all systems (e.g. CentOS/RHEL, stable Debian, etc) you need to build on a fairly old distro. And then you also get older ld etc as well. It would be great if you could tell rust & gcc (for native dependencies) to target an older glibc than the system one, that would solve a lot of issues.
In GCC/Clang, can happen with . is to use modern GCC/Clang style . I am not sure why is related to the problem. I think I should keep arguing for for all targets, not just non-x86. is prone to cause such problems for GNU ld and possibly mold.

I apologize to everyone, forgot about this issue. I can state that this issue is closed and no longer relevant. suggestion (as a workaround) and pull request fixed the issue.
