Updated Tumbleweed and started getting strange internal compiler errors when using g++. I didn't make any changes to the code that has compiled and build successfully earlier.

/usr/include/c++/8/limits:1599:7:internal compiler error: Illegal instruction
min() _GLIBCXX_USE_NOEXCEPT { return __FLT_MIN__; }

Please submit a full bug report,
