Sorry about the breakage.
I wasn't able to reproduce the failures myself, but the following
patch seems plausible as a fix; does it fix the affected
configurations?
gcc/ChangeLog:
PR bootstrap/117677
* json-parsing.cc (selftest::test_parse_number): Replace
ASSERT_EQ of 'double' values with ASSERT_NEAR. Eliminate
ASSERT_PRINT_EQ for such values.
* selftest.h (ASSERT_NEAR): New.
(ASSERT_NEAR_AT): New.
