When compiling some Fuchsia code for RISC-V, we found that enabling -fstack-clash-protection started causing our builders to time out. When investigating locally, I found that the build would not complete, even after more than a full day. Typically these files compile on the order of seconds, so there seems to be something wrong in the RISC-V implementation of stack clash protection. Note: we don't see these issues on x86_64 or Aarch64.
I'm uploading a reproducer, but this I haven't had a chance to reduce it yet.
