Hello.
I have isolated the issue: it is the fused-multiply-add instruction
set (FMA on Intel processors). Running -march=skylake -mno-fma not
only does not hang, but passes make check-all (using R's native BLAS).
My intuition remains that something in the new more precise ebd0 code

Hello, Martin et. al.
I apologize for top posting, but I believe I have tracked down the
difference why last time my build worked and now it hangs on
`dchisq(c(Inf, 1e80, 1e50, 1e40), df=10, ncp=1)`. and it's NOT the
BLAS. I built against both 3.15 AND R's vanilla and it hung both
times. The

Do you see this same hang in a build of R with debug symbols? Can you
try running R with GDB, or even WinDbg or another debugger, to see
what the call stack looks like when the hang occurs? Does the hang
depend on the number of threads used by OpenBLAS?
On the off chance it's relevant, I've seen

I am building r-devel on Windows 10 64bit using Jeroen's mingw system,
and I am finding that my make check-devel hangs on the above issue.
Everything is vanila except that I am using OpenBLAS 0.3.18. I have
been using OpenBLAS for over a decade and have not had this issue
before. Is there anything
