[Pharo-users] Pharo 61 crashes on iceberg history

I'm almost sure this is not the right place to report it. Im having a vm crash when looking at the history of a repository on iceberg. urpharo: malloc.c:2394: sysmalloc: Assertion `(old_top == initial_top (av)

&& old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed. ./pharo-ui: line 11: 2011 Aborted (core dumped) "$DIR"/"pharo-vm/pharo" "$@"

Pharo downloaded from get.pharo.org/64/ on Ubuntu 16.04 (64bit) Has somebody had this problem? Where's the right place to report this? Thanks, Julián
