I'm not quite sure what you meant by "above release/2.28.master" and "on 
release/2.28.master just below the committed patch". However, one 
possible explanation for an infloop if the patch is improperly installed 
so that time/mktime.c is compiled for glibc without _LIBC being defined; 
in that case mktime's body could be just '__tzset (); return mktime 
(tp);' which would infloop. You can investigate this by disassembling 
mktime.
