It maybe comes from glibc226's new feature, i.e. "128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE 754-2008) and ISO/IEC TS 18661-3:2015" . (see below, pls) - So, if possible, would like to withdraw from adopting glibc2.26 (and - switch back to glibc2.24)? + switch back to glibc2.24 or glibc 2.25)? evidence ---------- 1.
