Bug ID: 94503
Summary: ICE in saved_diagnostic, at
analyzer/diagnostic-manager.cc:84
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: analyzer

Target Milestone: ---
g++-10.0.1-alpha20200405 snapshot (g:2a1a0c8c0db0aae50a2cebce59bd64334cd6ba2a)
ICEs when compiling the following testcase, reduced from
libstdc++-v3/testsuite/19_diagnostics/system_error/what-big.cc, w/ -fanalyzer:
template <typename> class allocator {
public:
allocator(const allocator &);
allocator();
};
template <typename> struct allocator_traits;
template <typename _Tp> struct allocator_traits<allocator<_Tp>> {
static allocator<_Tp> select_on_container_copy_construction() {
return allocator<_Tp>();
}
static allocator<_Tp> _S_select_on_copy() {
return select_on_container_copy_construction();
}
};
class basic_string {
struct _Alloc_hider {
_Alloc_hider(allocator<char>);
} _M_dataplus;
public:
basic_string(basic_string &)
: _M_dataplus(allocator_traits<allocator<char>>::_S_select_on_copy()) {}
} xxx(xxx);

The ICE (on C++ return-value-optimization) should be fixed by
g:808f4dfeb3a95f50f15e71148e5c1067f90a126d (for GCC 11). Marking this as
fixed.
