[Bug libfortran/40330] [4.5 Regression] incorrect IO

------- Comment #32 from jvdelisle at gcc dot gnu dot org  2009-07-05 02:12 -------
I am getting close now.  I have a patch that actually passes the CP2K test case
and regression testing.  It turns out that the parse_format_list function is
called recursively so one must be careful about relaying information back up to
the callers that a FMT_STRING token is involved and so don't save the parsed
data. There is a memory leak remaining, but I know exactly what it is and what
to do about it.

The patch I am working on is really just a work around for the real problem. 
The real problem is that the pointer for literal strings in formats is
clobbered by the routine that writes it. My plan is to get the above mentioned
workaround patch finalized and then work toward eliminating this root problem
in a subsequent patch. The final fix will involve some re-constructive surgery
on the format node structure.
