Subject: [PATCH 17/42] libparted: Fix warnings from GCC 8 -Wunused-variable
|
|
and -Warray-bounds
|
|
|
|
GCC 8 reports two warnings as follows.
|
|
|
|
r/fat/bootsector.c: In function 'fat_boot_sector_set_boot_code':
|
|
r/fat/bootsector.c:274:15: warning: unused variable 'fs_info' [-Wunused-variable]
|
|
FatSpecific* fs_info = FAT_SPECIFIC (fs);
|
|
^~~~~~~
|
|
In function 'memcpy',
|
|
inlined from 'fat_boot_sector_set_boot_code' at r/fat/bootsector.c:283:2:
|
|
/usr/include/bits/string_fortified.h:34:10: warning: '__builtin_memcpy' forming offset [126, 128] is out of the bounds [0, 125] [-Warray-bounds]
|
|
return __builtin___memcpy_chk (__dest, __src, __len, __bos0 (__dest));
|
|
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
To avoid the warnings, remove the unused variable. Use strcpy in place of
|
|
memcpy checking copy length.
