Is 4.5 also affected?

I was able to do a regression hunt. Going to r145209 just before the big I/O
patch eliminates the error. I then moved forward to r145636 and confirmed the
breakage.
I then manually removed the use of the forma

The two locations referenced by valgrind in transfer.c is in code that is
unchanged from 4.3, so I don't think that is where the problem is. However,
looking at the CP2K code line involved:

I'm testing now 4.4 which includes your fix, but I still see CP2K's restarts
failing. This looks like a second issue, different from what you've fixed so
far. The testcase

Proposed patch
This patch seems to fix it, will formally submit as soon as it regtests.

Confirmed on trunk.
This seems to be due to the format caching stuff?
The regression on the 4.4 branch would be explained by the I/O backport
(r147887).

compiled with trunk this is also buggy (with new bugs about dwarf2):

OK, now with easy testcase, as you'll notice from the output, the loop is
important:
IMPLICIT NONE
character(len=100) :: fmt1,str1,fmt2,str2
real*8 :: r(3)=0
integer :: i,iunit
fmt1="(T2,A2,"
str1="a"
iunit=6
DO i=1,10

OK, a good hint from valgrind. The following error is present if I use 4.4.1
but not if I link against the runtime from 4.4.0:
==30712== Invalid read of size 1
==30712==at 0x4A22DF9: strncmp (mc_replace_strmem.c:314)

unfortunately trunk currently fails for other reasons. I'll try to look into
that afterwards.
