Bug ID: 89312
Summary: snprintf warning is unparsable and not confusing
Product: gcc
Version: 7.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: martin at netbsd dot org
Target Milestone: ---
Gcc 7 has a new warning:
partman.c:1908:12: error: ' (' directive output may be truncated writing 2
bytes into a region of size between 1 and 255 [-Werror=format-truncation=]
"%s (%s, %s-%d)",
^~
I am not a native speaker so this may be a lanugage barrirer, but I completely
fail to parse what it is trying to tell me here.
Obviously as I am using snprintf I am aware that truncation of the output could
happen (and happy with it). There is no point in gcc warning about this
(different to cases like strncpy truncation). The function is standard defined
and safe, why warn at all here?
