Gentoo Linux. Fresh ecl-10.4.1 configured with
--with-system-gmp --enable-boehm=system --enable-longdouble --enable-gengc --enable-precisegc --enable-threads --enable-unicode
Please do not use unstable flags. --enable-precisegc and --enable-gengc are there for convenience, so that people interested in developing ECL can use and test them. --enable-gengc and --enable-threads are having incompatibilities.
Besides this, it is not recommended to use --enable-threads if you are just building Maxima. Threads cause a significant overhead for all applications and Maxima is a single-threaded one!
