You may want to upgrade; the latest version is 8.23, and there HAVE been
sort bug fixes in the meantime.  However, for your particular issue,
what you have found is not a bug in sort but in your usage.

Newer builds of sort include a --debug flag that show you what is going on:

$ printf 'l.c\nlD.h\nl.h\n' | sort --debug
sort: using ‘en_US.UTF-8’ sorting rules
l.c
___
lD.h
____
l.h
___

$ printf 'l.c\nlD.h\nl.h\n' | LC_ALL=C sort --debug
sort: using simple byte comparison
l.c
___
l.h
___
lD.h
____


You have encountered a FAQ:
https://www.gnu.org/software/coreutils/faq/coreutils-faq.html#Sort-does-not-sort-in-normal-order_0021

Your current locale has chosen a collation sequence that is case
insensitive and ignores punctuation, so sort IS sorting correctly.  Set
LC_ALL in the environment of sort to a different locale if you want
bytewise sorting.
