this patch broke Solaris bootstrap (both 32 and 64-bit sparc and x86): /vol/gcc/src/hg/master/local/gcc/gcc.c: In function 'bool check_offload_target_name(const char*, ptrdiff_t)': /vol/gcc/src/hg/master/local/gcc/gcc.c:4010:23: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=] 4010 | cand[n - c] = '\0'; | ~~~~~~~~~~~~^~~~~~ In file included from /vol/gcc/src/hg/master/local/gcc/system.h:706, from /vol/gcc/src/hg/master/local/gcc/gcc.c:31: /vol/gcc/src/hg/master/local/gcc/../include/libiberty.h:733:36: note: at offset 1 into destination object of size 1 allocated by '__builtin_alloca' 733 | # define alloca(x) __builtin_alloca(x) | ~~~~~~~~~~~~~~~~^~~ /vol/gcc/src/hg/master/local/gcc/gcc.c:4000:29: note: in expansion of macro 'alloca' 4000 | char *cand = (char *) alloca (strlen (OFFLOAD_TARGETS) + 1); | ^~~~~~ Rainer -- ----------------------------------------------------------------------------- Rainer Orth, Center for Biotechnology, Bielefeld University
