It looks like the value of ada-keywords is not a sequence but the
result of a previous evaluation of regexp-opt.  The valud of
ada-keywords on my emacs is (C-h v ada-keywords):

ada-keywords is a variable defined in ‘ada-mode.el’.
Its value is
("abort" "abs" "accept" "access" "all" "and" "array" "at" "begin" 
"body" "case" "constant" "declare" "delay" "delta" "digits" "do" "else" 
"elsif" "end" "entry" "exception" "exit" "for" "function" "generic" 
"goto" "if" "in" "is" "limited" "loop" "mod" "new" "not" "null" "of" 
"or" "others" "out" "package" "pragma" "private" "procedure" "raise" 
"range" "record" "rem" "renames" "return" "reverse" "select" "separate" 
"subtype" "task" "terminate" "then" "type" "use" "when" "while" "with" 
"xor" "abstract" "aliased" "protected" "requeue" "tagged" "until" 
"interface" "overriding" "synchronized" "some")

If I now do M-: (regexp-opt ada-keywords t) I get the regexp
your stack trace says is the argument to regexp-opt.

I suspect interference between ada-mode 4 and ada-mode 5; you
should disable ada-mode 4 completely before you load ada-mode 5.

Hope this helps
