The FuncCode is not visible. It’s some random number.
Console output is:
LyXAction.cpp (3825): action: is not known.
(lldb) print action
(lyx::FuncCode) $0 = 335544320
(lldb) up
(lldb) print cmd
(const lyx::FuncRequest) $1 = (action_ = LFUN_CHAR_BACKWARD, argument_ = L"
翣\U0000fffd𧿣\U0000fffd\U0000fffdᒄ\x01$\0$\0“,
origin_ = 32, x_ = 32, y_ = 32, button_ = 32)
(lldb) print cmd.action()
(lyx::FuncCode) $2 = LFUN_CHAR_BACKWARD
Really weird.

I tried to catch it by enabling the malloc debugger. The crash is gone
(perhaps because of the multiples of 16 boundaries). Instead of I get
another one later when exploring the menus items.
