Package: rust-hdrhistogram Version: 7.5.0-1 Severity: serious
I recently updated the hdrhistogram package and as part of that I resolved the issues that were blocking the tests from running on as autopkgtests.
Unfortunately when running the autopkgtests on i386 two tests failed, I can also reproduce this locally.

|I strongly suspect these failures are related to the quirky behaviour of the x87 FPU, but I have no idea how to debug them further. I also don't know how to judge the likely impact of this issue on real-world application code. I have reported the issue upstream athttps://github.com/HdrHistogram/HdrHistogram_rust/issues/111
