Re: gcc bug: convert_move -O3

oops.
Not yet tested for other gcc versions,
but I know that it worked for previous perl/gcc versions.
Maybe just that previous perls didn't use -O3

$ gcc -v

gcc version 3.3.3 (cygwin special)

easy reproducible testcase:

cat > gccO3bug.c

static int hack30_pray(ax, items, func)
int ax;
int items;
void *func;
{
    return 0;
}
int main () {
  int ax, items;
  void * symref;
  float num;
  num = ((*((float (*)()) hack30_pray))(ax,items,symref));
  return 0;
}
^D

gcc -c -O3 gccO3bug.c
internal compiler error: in convert_move, at expr.c:597


With gcc-3.4.4 I get:

$ gcc -O3 -c gccO3bug.c
gccO3bug.c: In function `main':
gccO3bug.c:13: warning: function called through a non-compatible type
gccO3bug.c:13: note: if this code is reached, the program will abort

S.th. wrong with your testcase?

Can you try if the Perl extension compiles with gcc 3.4.4, and please
send me a patch for the testsuite:

Running make test

not ok 2

Giving up.
