+ The compiler now properly annotates the code in value in + the 'after' clause for a 'try' so that + Dialyzer no longer generates a false warning for an + unmatched return.

+ + +

+ Some case statements where no clause would match could + cause an internal error in the compiler. (Thanks to Erik + Soe Sorensen for reporting this bug.)

+

+ + +

+ With --Wunmatched_returns, dialyzer will no longer + warn when the value of a list comprehension is ignored, + provided that the each value in the list would be an + atomic value (such as integer or atoms, as opposed to + tuples and lists). Example: ignoring '[io:format(...) + || ...]' will not cause a warning, while ignoring + '[file:close(Fd) || ...]' will.

+

+ For information on how to use Maps please see the + Reference + Manual.

Compiler 6.0.3 + +
Fixed Bugs and Malfunctions + + +

+ An complicated guard expression in a function call could + crash the compiler. (Thanks to Thomas Arts for reporting + this bug.)

+

+ Own Id: OTP-13208

+ + +

Constructing a map in a guard in a catch could crash + the compiler. (Thanks to Thomas Arts for reporting this + bug.)

+

+ Own Id: OTP-13223

+ + +

Updating a fun as if it were a map would cause the + compiler to crash. (Thanks to Thomas Arts for reporting + this bug.)

+

+ Own Id: OTP-13231

+ + +

+ Fix pretty printing of Core Maps

+

+ Literal maps could cause Dialyzer to crash when pretty + printing the results.

+

+ Own Id: OTP-13238

+ + +

+ A complex combination of bit syntax matching operations + would cause an internal consistency check failure during + compilation. (Thanks to Jose Valim for reporting this + bug.)

Bitstring comprehensions have been generalized to + allow arbitrary expressions in the construction part.
