For some Rust crates, like building p384 in DEBUG mode, a SIGSEGV
is encountered as follows:

      note: rustc unexpectedly overflo= wed its stack! this is a bug
      note: maximum backtrace depth re= ached, frames may have been lost
      note: we would appreciate a repo= rt athttps://github.com/rust-lang/rust
      note: backtrace dumped due to SI= GSEGV! resuming signal
      error: could not compile `p384` = (lib)

Setting RUST_MIN_STACK to 8MB conditionally for DEBUG builds only handles
the stack overflow and SIGSEGV.

s/to 8MB/from 2MB to 8MB/

Best to explain what the current default value in your commit log in case the rust devs increase the limit some day.

Is there an issue open for the p384 crate to reconsider their stack abuse?

If so, please include that link. If not, create one and link that.


Thanks Yashe,

The second issue mentioned in the references is still open but there aren't any recent updates.
Also, Sundeep had reported the same issue in rust and llvm before:

https://github.com/rust-lang/rust/issues/113612<= /a> (closed as not planned)

https://github.com/llvm/llvm-project/issues/76= 920 (open, but again points to https://github.com/rust-lang/rust/issu= es/122357)

Let me know, if you want me to send a v2?


We discussed this issue and agreed that since it doesn't affect YP AB since there are no DEBUG builds done there
and more importantly since it's really a work-around rather than a fix, we'll continue to work with upstream p384
crate owners to resolve the issue. Forcing users to change the stack size, even for debug builds, is not a good policy
and hopefully some of the code-generation tools that are inputs to p384 can be adjusted to reduce stack usage.
