Problem
Platform tools v1.39 shipped with Solana v1.18 contains a bug in the discriminator size and in the stack allocation.
The new version contains a fix for the incorrect enum size introduced in Rust 1.72: anza-xyz/rust#90. This could cause programs to stop working, if developers build them with new tools.
In addition, v1.39 introduced changes in the SROA (Scalar Replacement of Aggregates) pass, which caused multiple functions to utilize more stack space than before: #252. v1.41 fixes this as well.
Summary of Changes
This is a back port of solana-labs#35330 to v1.18.
