crash while compiling
Created an attachment (id=6170) [edit] file produced by gcc with option -save-temps gcc building options was: make CFLAGS='-O2 -march=pentium4 -mcpu=pentium4 -msse2 -funroll-all-loops -mpreferred-stack-boundary=4 -mfpmath=sse -malign-double -momit-leaf-frame-pointer -fomit-frame-pointer -fforce-mem -fforce-addr -falign-functions -falign-labels -falign-loops -falign-jumps -frename-registers -fno-cprop-registers -ffast-math' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap
Confirmed a regression but I have not reduced it yet.
The testcase is here: ----------------- struct S { template <class T> S(const T &e); }; int operator *(const double, const S &); template <class T> struct X { enum { SIXTY_FOUR=64 }; struct node { unsigned char *ptr[sizeof(T)*SIXTY_FOUR]; void add(const T &obj) {} }; node *head; }; void foo(int &c) { X<int>().head->add(c); } ------------------ g/x> /home/bangerth/bin/gcc-3.3.4-pre/bin/c++ -c x.cc g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc x.cc: In instantiation of `X<int>::node': x.cc:20: instantiated from here x.cc:12: internal compiler error: in instantiate_template, at cp/pt.c:8669 Please submit a full bug report, with preprocessed source if appropriate.

Reduced a little further: struct S { template <class T> S(const T &e); }; int operator *(const double, const S &); template <class T> struct X { enum { SIXTY_FOUR=64 }; struct node { unsigned char *ptr[sizeof(T)*SIXTY_FOUR]; // <-- catching operator* from above? void d() {} }; node *head; }; template struct X<int>;
