Hi Trupti,

I assume then, that adding -fno-finite-math-only to

export DEB_CFLAGS_MAINT_APPEND =

in debian/rules should fix the problem?


I tried this locally on amd64, and cannot detect
any performance hit, so I am tempted to make this
a general change, not just specific to ppc64el

Thanks for your assistance with this bug.
