Why does LO calc shutdown when copy and pasting cells? Is it a known bug?

When copy/pasting large quantities of cells [in my case from a csv dump file to another ods file] LibreOffice unexpectedly shuts down. This has made newer versions of LO unusable for me. This is probably not the best place to leave a bug report, but it is indeed repeated behavior with 4.4.x [I tried both 1 & 2 so far], but copy/paste works just fine [without unexpected shutdown] in 4.3.6 [Windows 7, 64 bit]. So I’ve just been uninstalling and rolling back for now. Just thought it bears mentioning and wondered if other users have experienced same. So, basically, How do I file an official bug report? and Who else is affected?

I did such. ref: https://bugs.documentfoundation.org/show_bug.cgi?id=90483 Turned out it was my video card drivers that needed an update. All is well now.
