on ghc 8.6.5 cabal install hmatrix-tests fails with

[3 of 4] Compiling Numeric.LinearAlgebra.Tests ( src/Numeric/LinearAlgebra/Tests.hs, dist/build/Numeric/LinearAlgebra/Tests.p_o )
Simplifier ticks exhausted
When trying UnfoldingDone $j_s1mHf
To increase the limit, use -fsimpl-tick-factor=N (default 100).

If you need to increase the limit substantially, please file a
bug report and indicate the factor you needed.

If GHC was unable to complete compilation even with a very large factor
(a thousand or more), please consult the "Known bugs or infelicities"
section in the Users Guide before filing a report. There are a
few situations unlikely to occur in practical programs for which
simplifier non-termination has been judged acceptable.

To see detailed counts use -ddump-simpl-stats
Total ticks: 4513444
cabal: Leaving directory '/var/folders/df/5d_dsdrx1dn4j30ktsgn8blh0000gp/T/cabal-tmp-3611/hmatrix-tests-0.19.0.0'
cabal: Error: some packages failed to install:
hmatrix-tests-0.19.0.0-CBikoZo0LFRBCtRsbHuMzR failed during the building
phase. The exception was:
ExitFailure 1

Can anybody install it on ghc 8.6.5? Also fails if I install with tick-factor of 200. With tick factor of 1000 it was consuming over 50 gb of (virtual) memory before I killed it.

I accidentally closed this but it should still be open but I can't see how to reopen it so opening a new issue.

I got it to install without any modification, with lts-13.21 (so ghc 8.6.5)
