6.0.0 crash at high precision mul?

[Torbjörn Granlund]

Although the crash might happen in GMP, when you call via another
library you need to ask the authors of that library for debugging help.

  - Calling mpfr_sin(2) at 1,000,000 bits precision works when running on the main thread.

  - The same call crashes when running on a separate thread.

To me, these facts point away from mpfr and gmp.  It sounds very much
like a problem with your code, specifically its system limits
allocation.
