Hello again, without the --endable-timer option, I have managed to compile hugs. Nevertheless, I was not successfull with doc. OK, I don't care about it, but anyway... I've run serveral tests. One of them is appended - for trial just type cesty (1,1) - it's a kind of state-space search implementation (horse problem) made by a student long time ago, without any optimization, for testing very good. My older hugs interpreter stops with error: ERROR - Control stack overflow GHCi stops with the same error: *** Exception: stack overflow That's OK, really, that's correct behavior after printing some results. Nevertheless, the new hugs compilation stops with this: Segmentation Fault(coredump) And that's probably not the correct end. May I do something wrong? I've thought that configure + make + make install_all_but_docs (no doc compiled) should work. Sorry for bothering if this is trivial or off topic.
