When a large "irregular" (e.g. i96) integer call argument is converted to indirect, 64-bit parts are stored to the stack. The full stack space (e.g. i128) was not allocated prior to this patch, but rather just the exact space of the original type. This caused neighboring values on the stack to be overwritten. Thanks to Josh Stone for reporting this.

This is a backport for rust-lang/rust#80810, targeting Rust 1.51-beta.
When a large "irregular" (e.g. i96) integer call argument is converted to
indirect, 64-bit parts are stored to the stack. The full stack space
(e.g. i128) was not allocated prior to this patch, but rather just the exact
space of the original type. This caused neighboring values on the stack to be
overwritten.
