--- Comment #2 from Manuel LÃpez-IbÃÃez <manu at gcc dot gnu.org> ---
The gimple we build is very strange:
switch (xD.2336) <default: <D.2342>, case 1: <D.2340>>
{
<D.2340>:
{
struct AD.2324 tmpD.2341;
try
{
try
{
D.2345 = 1;
return D.2345;
}
finally
{
# USE = anything
# CLB = anything
__comp_dtor D.2329 (&tmpD.2341);
}
}
finally
{
tmpD.2341 = {CLOBBER};
}
}
goto <D.2343>;
<D.2342>:
D.2345 = 0;
return D.2345;
}
<D.2343>:
}
}
That goto doesn't make much sense.
