            Bug ID: 109696
           Summary: ice: tree check fail
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

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
    7 | wait_for_reply_avg() { sprint_tm(wait_for_reply_avg); }
      | ^~~~~~~~~~~~~~~~~~
0x115a4fa tree_class_check_failed(tree_node const*, tree_code_class, char
const*, int, char const*)
        ../../trunk.year/gcc/tree.cc:8948
0x1183d13 tree_class_check(tree_node*, tree_code_class, char const*, int, char
const*)
        ../../trunk.year/gcc/tree.h:3663
0x1183d13 irange::verify_range()
        ../../trunk.year/gcc/value-range.cc:1060

It was fine yesterday:

$ ~/gcc/results.20230501.asan.ubsan/bin/gcc -c -w -O2 bug915.c
$

I suspect this is another one for Aldy.

Started with r14-377-gc92b8be9b52b7e0de5ad
Cleaned up testcase:
void
foo (long x)
{
  char buf;
  double t = x;
  if (t)
    __builtin_sprintf ((char *) (__INTPTR_TYPE__) buf, "");
}

void
bar (int x)
{
  foo (x);
}
