MacRuby on Rails #20110314-1
Assertion failed: *1, function pop_current_exception, file vm.cpp, line 3434.
エラーが発生しているのはvm.cppの以下の関数。
void RoxorVM::pop_current_exception(int pos) { RoxorSpecialException *sexc = get_special_exc(); if (sexc != NULL) { return; } assert((size_t)pos < current_exceptions.size()); std::vector<VALUE>::iterator iter = current_exceptions.end() - (pos + 1); VALUE exc = *iter; current_exceptions.erase(iter); GC_RELEASE(exc); //printf("POP (%d) %p %s\n", pos, (void *)exc, RSTRING_PTR(rb_inspect(exc))); }
コアダンプさせて、gdbなどでおっかける。

Cレベルのbtではよく分からなかったのでRubyレベルのバックトレースを出力させてみる。
scaffoldとserverは同じ場所でエラーになっているように見える。

上記のバックトレースのうち、以下の部分があやしい。コードを見てみる。

bundle_path.to_sは"/Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2"であり、作成済み。上記のバックトレースは、FileUtils.mkdir_pの処理中にディレクトリ作成済みかどうかをチェックしているだけであった。
