Bug ID: 112869
Summary: [14 regression] ICE at gimplify_expr, at
gimplify.cc:17531 on libopenmpt-0.7.3
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: slyfox at gcc dot gnu.org
Target Milestone: ---
Initially observed ICE on gcc-master at r14-6191-g9c3a880feecf81 compiling
libopenmpt-0.7.3.
Extracted example:
$ cat a.cpp.cpp
void min(long, long);
template <class T> void Binaryread(int &, T, unsigned long);
template <> void Binaryread(int &, float, unsigned long bytecount) {
min(bytecount, sizeof(int));
}
Crashing:
$ g++ -std=c++20 -c a.cpp.cpp -o a.o
a.cpp.cpp: In function 'void Binaryread(int&, T, long unsigned int) [with T =
float]':
a.cpp.cpp:4:18: internal compiler error: in gimplify_expr, at gimplify.cc:17531
4 | min(bytecount, sizeof(int));
