Bug#361883: FTBFS with GCC 4.2: tpow test fails
Package: mpfr
Version: 2.2.0.dfsg.1-4
Your package fails to build with GCC 4.2. Version 4.2 has not been
released yet but I'm building with a snapshot in order to find errors
and give people an advance warning. The tpow test fails when I
compile your package with a 4.2 snapshot from 20060325, but not with
4.0.3 or 4.1.0. I'm not sure whether this is a bug in your package or
in the compiler - I tried removin the -O3 from Makefile but it still
shows the problem. Do you think you can investigate, and in the case
it's a compiler bug come up with a minimal test case?
