Udało mi się znowu dość powtarzalnie wywołać ten błąd na Fedorze 19/i686 przy budowaniu paczki z 1.12.0-rc3. > Czy przy kompilacji były jakiekolwiek błędy?

Flagi configure: ./configure --build=i686-redhat-linux-gnu --host=i686-redhat-linux-gnu --program-prefix= --disable-dependency-tracking --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info --disable-silent-rules --disable-static --without-openssl --with-pthread Błędów kompilacji nie było.
