The offending line in Eigen looks reasonable: inline ei_scalar_quotient1_impl(const Scalar& other) : m_other(static_cast<Scalar>(1) / other) {} No inline assembly or anything suspicious. GCC crashes in void convert_move (rtx to, rtx from, int unsignedp). The function is documented as: /* Copy data from FROM to TO, where the machine modes are not the same. Both modes may be integer, or both may be floating, or both may be fixed-point. UNSIGNEDP should be nonzero if FROM is an unsigned type. This causes zero-extension instead of sign-extension. */ The assertion which fails is gcc_assert (to_real == from_real);. This checks for the constraint that "Both modes may be integer, or both may be floating", here we have a mix, so GCC is calling convert_move with invalid arguments. A backtrace might help, as might GCC internal representation dumps (both tree and RTL dumps), but in any case a bug needs to be filed against GCC. I'd suggest disabling building the testsuite for now if that gets the package to build, but filing a bug against GCC to get GCC fixed. -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ Fedora-package-review mailing list Fedora-package-review@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-package-review
