The following C++ program will not compile with g++ versions 3.4.1 or 3.5, I tried the ia64-hp-hpux11.22 platform as well as hppa-hp-hpux11.00. struct C { virtual void f() {} }; struct B {virtual ~B() {} }; class D : public B, public C { public: virtual void f() {} }; typedef void ( C::*FP)(); typedef void ( D::*D_f)(); int main() { D *d = new D(); C *c = d; const FP fptr = (FP) &D::f;; (d->* (D_f)fptr)(); } ----------------------------------- /usr/local/bin/g++ -c x.C x.C: In function `int main()': x.C:21: internal compiler error: in build_ptrmemfunc, at cp/typeck.c:5512 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions.
: Search converges between 2003-07-28-trunk (#307) and 2003-07-29-trunk (#308). Confirmed.
Working on a fix.
