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
