I get an ICE when building 502.gcc_r from SPEC2017 intrate for aarch64:
$ gcc -c -o dbxout.o -DSPEC -DNDEBUG -I. -I./include -I./spec_qsort -DSPEC_502
-DSPEC_AUTO_SUPPRESS_OPENMP -DIN_GCC -DHAVE_CONFIG_H     -DSPEC_LP64  dbxout.c

during GIMPLE pass: printf-return-value
dbxout.c: In function 'dbxout_stab_value_internal_label':

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.

Unfortunately this is not reproducible when compiling with -save-temps or when
using the preprocessed file, so I can't reduce it.
