Bug ID: 61957
Summary: Wrong -Warray-bounds warning depending on parameter
types
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: tavianator at gmail dot com
Created attachment 33205
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33205&action=edit
Test case
On x86-64 Linux, the attached testcase produces the duplicate spurious warning
with -O3 and -Wall:
$ gcc -std=c11 -O3 -Wall -c array-bounds.c
array-bounds.c: In function 'cofactor':
array-bounds.c:9:10: warning: array subscript is above array bounds
[-Warray-bounds]
n[k] = A[i][j];
^
array-bounds.c:9:10: warning: array subscript is above array bounds
[-Warray-bounds]
Interestingly, if the 'row' and 'col' parameters are changed to 'unsigned
long', the warning goes away.
