[Bug libgcj/22253] New: ICE while compiling libjava/gnu/gcj/xlib/natWindow.cc

[andreast at gcc dot gnu dot org]

I get the following ICE:

The config is this one, but I have to try if it fails also with xlib only.

Confirmed, reduced testcase:
struct allocator { ~allocator() {} };
struct _Vector_base
{
  struct _Vector_impl
  {
    int* _M_start;
    int* _M_finish;
    _Vector_impl()
      : _M_start(0), _M_finish(0)
    { }
  };
  _Vector_base(){}
  _Vector_impl _M_impl;
};
void setWMProtocols()
{
  allocator a;
  _Vector_base atomVector;
}


This also happens on i686-pc-linux-gnu with the reduced testcase.
Only -O2 -fnon-call-exceptions is needed to reproduce the bug.
I think VRP is not cleaning up the exceptions regions correctly.

This is a build bug because it blocks building with --enable-java-awt=gtk,xlib.

I should note that if we fix PR 21636, this becomes a latent bug.

I wonder why it's not caught by a tree verifier then.

Hm, seems to work now :)
At least for the build.

http://gcc.gnu.org/ml/gcc-testresults/2005-07/msg00144.html

Could one confirm if it works on x86 with the reduced tc?

Try with checking enabled, you will see it still fails.

Confused :)

http://gcc.gnu.org/ml/gcc-testresults/2005-07/msg00190.html

is the --enable-checking ok ?

Hmm, weird, oh well the reduced testcase still fails on the mainline.
