> Closing as fixed.
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 of comment #5 is working fine, with the update 4.4.1, but
CP2K runs still shows a valgrind warning:

linking to the 4.3.2 runtime still solves the issue. I hope you can have a look
at what might be wrong with these traces above, I don't have a testcase other
than CP2K right now, and the code is tricky to reduce at that point.
If you happen to have CP2K around, this is the testcase for the trace:
cp2k/tests/Fist/regtest-5> valgrind --tool=memcheck
../../../exe/Linux-x86-64-gfortran/cp2k.sdbg wat_freq.inp
