Buildbot failure, x86_gentoo_cfg1

This is failing currently. Its configure line is: ./configure --with-xemacs-compiler=g++ --with-mule --with-pdump --with-error-checking=all --with-debug=yes --with-bignum=gmp --with-xft=all --with-kkcc --with-newgc --with-union-type --with-optimization And it seems to be using gcc-5.4. The compile fails when temacs is run to byte compile. This error comes from bytecomp.el: Symbol's value as variable is void: wrapper # bind (stack-trace-on-signal debug-on-signal stack-trace-on-error debug-on-error) # (unwind-protect ...) (put wrapper (quote byte-compile) (function (lambda (form) (let* ((gensym (gensym)) (byte-compile-bound-variables (acons gensym byte-compile-global-bit byte-compile-bound-variables))) (setq byte-compile-output-preface (byte-compile-top-level (list (quote progn) (list (quote setq) gensym (list (quote progn) (second form))) byte-compile-output-preface) t (quote file))) (byte-compile-form (list (quote symbol-value) (list (quote quote) gensym)) nil))))) As far as I am concerned, this is very likely to be a compiler bug rather than a bug in the XEmacs code. I can’t reproduce it locally. I don’t intend to fix it, I can be more useful with other code. Is there any option for WONTFIX in the buildbot? If not, could we try changing the buildbot to be --without-optimizaiton?
