The upstream issue has no progress. Redhat Bugzilla has no progress yet. It looks either like a double free() or a memory corruption that could be possibly found by valgring. Is it serious enough to start a research? Note that we have no Modbus testing hardware. -- You are receiving this mail because: You are on the CC list for the bug.

I propose to do a version update. -- You are receiving this mail because: You are on the CC list for the bug.
