Title:
  mpfr is not compiled with --enable-thread-safe, and so crashes multi-
  threaded programs

Status in mpfr4 package in Ubuntu:
  Fix Released

Bug description:
  Please compile MPFR with  --enable-thread-safe during ./configure.
  Thread safety is not turned on by default, since MPFR supports
  multiple platforms, and some can't handle threads properly. If this is
  not done, then MPFR's cache variables are shared between threads,
  leading to a crash (see Section 4.7, Memory Handling, in the MPFR
  documentation).

  Technically, this is not a bug. But please do this, since it will save
  the next poor soul many frustrating hours debugging their code...
