    Hello,

    What is the difference between these builders and the other ones? The
    issue appears since 2.87, b/c since this version I run the test suite at the end of the build.


    https://db.debian.org/machines.cgi tells me that these are "Quad Core Loongson 3A4000", meanwhile the others are "Quad Core Loongson 3A3000". Not sure if that plays a role.

    Loongson 3A4000 CPU swapped the sNaN and qNaN representation compared to
    the original MIPS ABI. I guess a[i] contains a qNaN, which is
    interpreted as a sNaN on the 3A4000, causing the FPU exception.

    I have Cc:ed the porters so that can help you to find a solution to this issue.

    Regards
    Aurelien
