What's the value of _PY_SHORT_FLOAT_REPR? Look in pyconfig.h file.

The structure is defined in Include/internal/pycore_dtoa.h.

[vstinner]

Ah wait, the macro is defined in: Include/internal/pycore_pymath.h

//--- _PY_SHORT_FLOAT_REPR macro -------------------------------------------

// If we can't guarantee 53-bit precision, don't use the code
// in Python/dtoa.c, but fall back to standard code.  This
// means that repr of a float will be long (17 significant digits).
//
// Realistically, there are two things that could go wrong:
//
// (1) doubles aren't IEEE 754 doubles, or
// (2) we're on x86 with the rounding precision set to 64-bits
//     (extended precision), and we don't know how to change
//     the rounding precision.

    !defined(DOUBLE_IS_ARM_MIXED_ENDIAN_IEEE754)
#  define _PY_SHORT_FLOAT_REPR 0
#endif

// Double rounding is symptomatic of use of extended precision on x86.
// If we're seeing double rounding, and we don't have any mechanism available
// for changing the FPU rounding precision, then don't use Python/dtoa.c.

The same happens when building for armv7l-unknown-linux-musleabihf

[yu-re-ka]

and armv7l-unknown-linux-gnueabihf

[NickCao]

and riscv64-unknown-linux-gnu

[yu-re-ka]

bisected the failure on armv7l-unknown-linux-gnueabihf to 3c57971

Fixed by c3677be thank to @yu-re-ka. Backports will follow. Thanks for the report.
