Title:
gcc 8.2 reports stringop-truncation when building qemu
Status in QEMU:
Fix Released
Bug description:
QEMU 3.0
block/sheepdog.c: In function 'find_vdi_name':
block/sheepdog.c:1239:5: error: 'strncpy' specified bound 256 equals destination size [-Werror=stringop-truncation]
strncpy(buf + SD_MAX_VDI_LEN, tag, SD_MAX_VDI_TAG_LEN);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If this is the intended behavior, please suppress the warning. For
example:
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wstringop-truncation"
strncpy(buf + SD_MAX_VDI_LEN, tag, SD_MAX_VDI_TAG_LEN);
#pragma GCC diagnostic pop
This also happens on other sources, for example hw/acpi/core.c, so
another option is to suppress it globally on CFLAGS (-Wno-stringop-
truncation)
