Status: UNCONFIRMED
Severity: normal
Priority: P3

Target Milestone: ---
I tried to compile gcc/testsuite/g++.dg/cpp1z/inh-ctor23.C
with flag -O2 and recent gcc and it said this:
./g++.dg/cpp1z/inh-ctor23.C:10:7: internal compiler error: in
ipa_modify_formal_parameters, at ipa-prop.c:3979
Z z(0); // OK: initialization of Y does not invoke default constructor of X
^

va_heap, vl_ptr>)
