Hi, we got a report on Fedora about a crash for Fedora 23. (I am the initial reporter in case you wonder ;-) )
https://bugzilla.redhat.com/show_bug.cgi?id=1260976 The backtrace is available at https://bugzilla.redhat.com/attachment.cgi?id=1071287 The step that looks suspicious to me is the #12 in lyx::html::StartTag::~StartTag Fedora 23 is using gcc-5.1.1 with standard compliant strings, in case that matters. For me the crash is easily reproducible, it is enough to select some text and then to copy it or cut it, lyx always crashes. Regards, -- José Abílio
