Help with neovim segfault on mips64el (Loongson specific?)

Hi all,

Recently neovim has been segfaulting during tests in both the neovim[0] and
neovim-qt[1][2] builds.  This appears to be specific to Loongson
hardware, as the build[3] on mipsel-sil-01.d.o (Octeon) worked.  I'm
also unable to reproduce the problems on eller (another Octeon).

Does anyone have some insight into possible issues or would be willing
to look into the problem?

Cheers,
