For this C code:
sprint_tm(long ns) {
char buf;
double t = ns;
if (t)
sprintf(buf, "");
}
wait_for_reply_avg() { sprint_tm(wait_for_reply_avg); }
compiled by recent trunk gcc, does this:
$ ~/gcc/results.20230502.asan.ubsan/bin/gcc -c -w -O2 bug915.c
during IPA pass: inline
bug915.c:7:1: internal compiler error: tree check: expected class ‘type’, have
‘exceptional’ (error_mark) in verify_range, at value-range.cc:1060

It was fine yesterday:

I suspect this is another one for Aldy.
