Bug ID: 96554
Summary: -Wall does not include -Wnull-dereference
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: R.E.Wolff at BitWizard dot nl
Target Milestone: ---
As reported in c/96550, the fact that -Wall didn't include -Wnull-dereference
cost me a lot of time in trying to figure out what the problem was with my
code.
I add -Wall to get lots of warnings about potential bugs. if (a = 3) is an
example where a simple typo in the code leads to perfectly valid C, but such a
"high likelyhood of a bug" that a warning is warranted.
Same here: I wrote a bug that caused the compiler to a) not warn me and b) do
unexpected things. I think the -Wnull-dreference is a valid warning to enable
with -Wall.
