A corrective release of Firefox 152.0.1 is now available, addressing issues that led to crashes on systems with Intel processors based on the Raptor Lake microarchitecture. The problem arose from a CPU bug that caused incorrect handling of instructions generated for caching intermediate representation functions in the JIT compiler written in C++. Notably, similar issues with Intel Raptor Lake CPUs were resolved in the release of Firefox 151.0.1 a month ago. Previous problems manifested due to incorrect processing by Intel Raptor Lake processors of the instruction 'mov byte ptr [rsi + rdi + 1], ch', generated for code from the zlib-rs library written in Rust.
