Hard to reproduce and reduce... The pasted testcase gets you the scopeCall with -1 as line number. As soon as one of the fn declaration is commented, scopeCall vanishes. It is observed in avatar-js dumped stacks. function fail() { throw new Error("Strange..."); } var f2 = fail; var f3 = fail; var f4 = fail; var f5 = fail; try { fail(); }catch(err) { print(err.stack); }
