Bug ID: 126905
Summary: [17 Regression] ICE in type, at value-range.h:1088
during GIMPLE pass: threadfull with assume
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: bouncy12578 at gmail dot com
Target Milestone: ---

Compiler Explorer: https://godbolt.org/z/Mxs1YqevK
Known to fail: trunk
Known to work: 16.2
Compiler version:
Using built-in specs.

Thread model: posix
Supported LTO compression algorithms: zlib
gcc version 17.0.0 20260814 (experimental) (GCC)
Command line used:
g++ -O2 -g -masm=intel -mtune=generic -march=x86-64 test.cpp
Code to reproduce:
long a;
#define ASSUME(x) [[assume(x)]];
#include <algorithm>
void b(bool c, bool d) {
ASSUME(c + 3 == 3);
for (int i = 0; i < 3; i++)
a = std::max(d * c, (int)c) ? 4085320707 ? d : d : 0;
}
Note: This test case was automatically generated by a fuzzer and reduced.
Compiler output:
during GIMPLE pass: threadfull
