## Triage

### FCPs

1 rust-lang/rust T-libs FCPs

- merge rust.tf/115746 *Print thread ID in panic message if thread name is unknown* - (3 checkboxes left)

[the8472 (1)](https://rfcbot.rs/fcp/the8472), [joshtriplett (1)](https://rfcbot.rs/fcp/joshtriplett), [m-ou-se (1)](https://rfcbot.rs/fcp/m-ou-se)

### (Nominated) rust.tf/126557 *Add \`#\[track\_caller\]\` to allocating methods of \`Vec\` & \`VecDeque\`*

Accept the overhead (seems to be mostly compile-time).

### (Nominated) rust.tf/129491 *Pass \`fmt::Arguments\` by reference to \`PanicInfo\` and \`PanicMessage\`*

### (Nominated) rust.tf/129808 *Tracking peak total storage use*

Libs cares about:
- Final binary size
- Docs size
- Rustup component size

Although it's still mostly T-compiler

### (Waiting on team) rust.tf/128600 *repr(int) fieldless enums are ABI\-compatible with int*

### (Waiting on team) rust.tf/129201 *std: implement the \`random\` feature (alternative version)*

### (Regressions) rust.tf/119560 *\`cargo test\` performance regression on Windows on version 1.75.0*

### (Regressions) rust.tf/129895 `P-low` *\[QNX7.1\] \`std::fs::tests::symlink\_hard\_link\` broken on main*

### (Regressions) rust.tf/53340 *Performance regression in tight loop since rust 1.25*

### (Regressions) rust.tf/112180 *assertion failed: key as usize != KEY\_SENTVAL in DragonFly BSD*

### (Regressions) rust.tf/124216 `P-medium` *Performance regression: rustc failed to optimize \`\_mm256\_avg\_epu8\` after 1.75.0*

### (Regressions) rust.tf/125198 *regression: can't call method \`abs\` on ambiguous numeric type \`{float}\`*

### (Regressions) rust.tf/126685 *Regression in type inference between stable 1.79.0 and nightly\-2024\-06\-19*

### (Regressions) rust.tf/126766 *Nightly regression: \`panic::set\_hook()\` signature incompatible if used with core::panic::PanicInfo*

### (Regressions) rust.tf/127343 *regression: type annotations needed for Box\<\_\>*
