For background information, I am trying to track down a ICE (internal compiler error) in gcc (specifically x86_64-pc-linux-gnu-g++) when compiling boost-1.73.0. gcc has been built with debugging info, but the file I am reducing is part of boost. The current run has been going for over 48 hours and has so far reduced from 92792 lines/ 3267829 bytes to 12389 lines/585124 bytes. A minor issue (but probably not for creduce itself) is that the bug seems non-deterministic, so a single example may not fail every time. An earlier run (about 6 hours) came down to a single (not actually syntactically valid) line, and the current run is after applying a patch to gcc to fix that one. Additional info, in case it matters, is that the interestingness test is just grepping for "internal compiler error" in the gcc output.
I am not subscribed to either list, but will be watching the archives in case I need to subscribe to participate in any discussion.
Thank.
