error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.45.0 running on armv7-unknown-linux-gnueabihf

note: compiler flags: -Z threads=1 -Z ui-testing -Z deduplicate-diagnostics=no -Z unstable-options -C prefer-dynamic -C rpath -C debuginfo=0 -C linker=arm-linux-gnueabihf-gcc

query stack during panic:
thread panicked while processing panic. aborting.

------------------------------------------

[infinity0]

Upon further investigation it seems that these failures also occur on 32-bit powerpc so not arm-specific.

[infinity0]

Most (possibly all) of the error messages contain thread 'rustc' panicked at 'assertion failed: self.ptr <= self.end', /usr/src/rustc-1.45.0/src/libstd/macros.rs:13:23, @jonas-schievink can you please add the relevant macro-related tags?

[jonas-schievink]

Isn't that just pointing to one of the panic!-family macros?

[tmiasko]

The failing assertion looks like an issue that was fixed by #73237.

[infinity0]

@jonas-schievink from the history of some of those tests, they were moved from run-fail so I think panicing is the desired behaviour, however it appears in this case the panic is causing an ICE rather than "failing successfully".

@tmiasko OK thanks, I'll backport that and see if it solves the problem.

[jonas-schievink]

This is a metadata panic, actually
