Hello,

on Erlang R16B02 I've found that try ... catch constraction hidden compile
warning: "variable 'Sth' is unused". On Erlang R15B02 warning exists. The
sample at the attach. When I complile by Erlang R15B02 I have two warnings:
Eshell V5.9.1  (abort with ^G)
1> c(no_warning).
no_warning.erl:10: Warning: variable 'STh' is unused
no_warning.erl:22: Warning: variable 'STh' is unused
{ok,no_warning}

But when I compile by Erlang R16B02 I have only one warning:
Eshell V5.10.3  (abort with ^G)
1> c(no_warning).
no_warning.erl:22: Warning: variable 'STh' is unused
{ok,no_warning}

Anton
