--- Comment #8 from seurer at gcc dot gnu.org ---
I looked at where the code is hanging and it looks like it is hung in a loop
where it keeps calling memcpy with an incrementing by 1 length.
I set a breakpoint at the start of memcpy to break if the length was greater
than 9000 and when the breakpoint was hit just keeping hitting continue. It
was called with length 9001, 9002, 9003, ... There is nothing in the code that
does anything like this as far as I can tell and this doesn't happen with the
previous revision.
Is the call
s = transfer(vs, s)
expanded into an infinite loop? I don't know fortran so I have no idea what
that is supposed to do.
