+- duplocale used wrong malloc when malloc was replaced (1.2.2 regression)
+- fmaf rounded wrong on archs without FE_TOWARDZERO (all softfloat archs)
+- popen didn't honor requirement not to leak other popen pipe fds to child
+- aligned_alloc and variants crashed on allocation failure
+- dl_iterate_phdr reported incorrect module TLS pointers
+- mishandling of some inputs in acoshf and expm1f and functions using them
+- potentially wrong-sign zero in cproj functions at infinity
+- multiple bugs in legacy function cuserid
+- minor posix_spawn file actions API conformance issues
+- pthread_setname_np fd leak
+- out-of-bound read in zoneinfo handling with distant-past times
+- out-of-tree builds lacked generated debug cfi for x86 asm
