2パターンで。
パターン1
コード1:
import sequtils var x = cast[string](@[1, 2, 3, 4, 5])
出力1:
% $HOME/Nim/bin/nim -version Nim Compiler Version 0.11.2 (2015-05-20) [Linux: amd64] Copyright (c) 2006-2015 by Andreas Rumpf git hash: 45b6082c12dd6fc90a3dd3ca97e1ba157c3d6464 active boot switches: -d:release % $HOME/Nim/bin/nim c hoge.nim ..

(Attempt to read from nil?)
パターン2
コード2:
import sequtils echo cast[string](@[1, 2, 3, 4, 5])
% $HOME/Nim/bin/nim -version Nim Compiler Version 0.11.2 (2015-05-20) [Linux: amd64] Copyright (c) 2006-2015 by Andreas Rumpf git hash: 45b6082c12dd6fc90a3dd3ca97e1ba157c3d6464 active boot switches: -d:release % $HOME/Nim/bin/nim c fuga.nim .. (省略) Hint: operation successful (9696 lines compiled; 0.184 sec total; 14.143MB; Debug Build) [SuccessX] % ./fuga Traceback (most recent call last) fuga.nim(3) fuga SIGSEGV: Illegal storage access. (Attempt to read from nil?)
原因は同じっぽい気はするけれど、それぞれsegvがでた場所が違ったので一応わけてかいた。 もうちょっと調べて詳細を書く予定。(あくまで予定)
[追記]
これっぽい?
[追記2]
バグじゃなかったそうです。
