We can't reproduce this with the dynamic builds of TurboFloat. We haven't tested the static builds to try to reproduce this (because (a) the static versions are identical, functionally, to the dynamic version and (b) static builds can be interfered with by linking with alternative libraries and overwriting our internal code).
Try again with the dynamic version of TurboFloat. If you're still getting an error then we'll need more information (full stack trace, a reproducible example, etc.).
If you're not getting an error with the dynamic version of TurboFloat, then analyze how you're linking the static TurboFloat. First, make sure you're *only* using our static versions of libraries (don't swap things out -- we carefully compile things so they work, just because we depend on publicly available libraries does not mean they can be swapped out without consequences). And also make sure you're using the latest version of TurboFloat.
