Bug ID: 105779
Summary: internal_error on passing a pointer to static function
to another function
Product: gcc
Version: 12.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bart at bartjanssens dot org
Target Milestone: ---
Created attachment 53054
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53054&action=edit
Minimal example to reproduce this
Compiling the attached test case fails, explicitly adding & on line 23 to
indicate that method takes a pointer to a function solves the problem, but I
believe both should compile (and did prior to GCC 12), and certainly not crash.
Compile command: g++ -Wall -Wextra test-pointer.cpp
Output:
during RTL pass: expand
test-pointer.cpp: In member function ‘int
WrapSmartPointer::operator()(TypeWrapperT&&) [with TypeWrapperT = IntWrapper]’:
test-pointer.cpp:23:18: internal compiler error: Segmentation fault
23 | return method(DereferenceSmartPointer<WrappedT>::apply); //
method(&DereferenceSmartPointer<WrappedT>::apply) works
