Bug ID: 118629
Summary: ice in cp_parser_expression_statement, at
cp/parser.cc:13584
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
>From the clang C++ testsuite, file SemaCXX/crash-GH121274.cpp
does this with g++:
test $ ~/gcc/results/bin/gcc -c SemaCXX/crash-GH121274.cpp
SemaCXX/crash-GH121274.cpp: In function ‘void foo()’:
SemaCXX/crash-GH121274.cpp:8:11: internal compiler error: in
cp_parser_expression_statement, at cp/parser.cc:13584

Source code is
// RUN: %clang_cc1 -std=c++11 -verify %s
// expected-no-diagnostics
// Do not crash when __PRETTY_FUNCTION__ appears in the trailing return type of
the lambda
void foo() {
[]() -> decltype(static_cast<const char*>(__PRETTY_FUNCTION__)) {
return nullptr;
}();
#ifdef MS
[]() -> decltype(static_cast<const char*>(__FUNCSIG__)) {
return nullptr;
}();
#endif
}
The clang test suite is at
https://github.com/llvm/llvm-project/tree/main/clang/test
The code first goes wrong in g++ sometime before g:0b06abe027a78681
