TypeScript: TypeScript is crashed by using too much memory

This crash is caused by a few codes. Is this correct behavior?

TypeScript Version:

1.9.0-dev.20160609

Code

https://github.com/falsandtru/spica/tree/v0.0.6 https://travis-ci.org/falsandtru/spica/builds/136372602 https://github.com/falsandtru/spica/blob/v0.0.6/src/lib/monad/sequence.ts

$ $(npm bin)/tsc --noEmit -t es5 --diagnostics typings/tsd.d.ts typings/spica.d.ts typings/lib.ex.d.ts spica.ts

The compiler uses too many symbols, types, memory and Check time only for implementation of interfaces.

- export class Sequence<T, S> extends Monad<T> implements ISequence<T, S> {
+ export class Sequence<T, S> extends Monad<T> {

- Symbols:       1964595
+ Symbols:        892012
- Types:          529786

I found a solution.

before:

$ $(npm bin)/tsc --noEmit -t es5 --diagnostics typings/tsd.d.ts typings/spica.d
.ts typings/lib.ex.d.ts spica.ts
Files:              34
Lines:           19533
Nodes:           94018
Identifiers:     35814
Symbols:       1964595
Types:          529786
Memory used:   828809K
I/O read:        0.03s
I/O write:       0.00s
Parse time:      0.88s
Bind time:       0.58s
Check time:     28.43s
Emit time:       0.00s
Total time:     29.89s

after:

- export class Sequence<T, S> extends Monad<T> implements ISequence<T, S> {
+ export class Sequence<T, S> extends Monad<T> {

$ $(npm bin)/tsc --noEmit -t es5 --diagnostics typings/tsd.d.ts typings/spica.d
.ts typings/lib.ex.d.ts spica.ts

I/O write:       0.00s

Check time:      5.84s

Is this a correct behavior? It seems to leak Symbols and Types. I think, interfaces shouldn’t impair the performance.
