@golang/ios Was the system linker updated recently? This looks like a failure with the system linker specifically. (It would also be helpful to know what version of the linker is being used.)

[mknyszek]

Even if the Go toolchain is invoking the system linker incorrectly, it should be erroring out cleanly, but this is clearly an internal assert failing. It could also be something wrong with the platform because it's a write call that's failing.
