I'm testing release branches with ../configure --enable-languages=default,ada,obj-c++,lto,go,brig,d --enable-checking=yes,rtl,extra too, and saw (last time I've bootstrapped/regtested gcc-9-branch this way was Oct 21st though): ../../gcc/machmode.h: In function ‘dw_loc_descr_node* mem_loc_descriptor(rtx, machine_mode, machine_mode, var_init_status)’: ../../gcc/machmode.h:520:42: warning: ‘int_mode’ may be used uninitialized in this function [-Wmaybe-uninitialized] 520 | ? mode_size_inline (mode) : mode_size[mode]); | ^~~~ ../../gcc/dwarf2out.c:15464:19: note: ‘int_mode’ was declared here 15464 | scalar_int_mode int_mode, inner_mode, op1_mode; | ^~~~~~~~ and no fatal error. Are you using --enable-werror or something similar in addition? Jakub
