[Solved] [] operator in std::map is giving me segmentation fault [closed]

Maybe your myMap is no longer accessible. For instance, it might be a reference to a deleted pointer, or, much more probable, a member variable of an already deleted class: class MyClass { public: selfInsert(std::string myKey) { if(!myKey.empty()) { myMap[myKey] = this; } } private: std::map<std::string, myClass*> myMap; } int main() { MyClass *a = … Read more

[Solved] Creating a JavaScript global array with static elements?

The problem isn’t that removeFunction doesn’t have access to bigArray. The problem is in your onclick attribute, and the id you’re putting on the link: $(‘#div’).append(“<a href=”#” id=’bigArray[i]’ onclick=’removeFunction(bigArray[i])’>Element bigArray[i]</a><br />”); In the onclick, you’re referring to i, but A) I’m guessing i isn’t a global, and B) Even if it is, it will not … Read more

[Solved] Using NSDateFormatter in objective-C [duplicate]

This will give you the correct NSDate. Next, you need to create a new date formatter with the format @”dd.M.yyyy” (or @”d.M.yyyy” if you want to remove … Read more

[Solved] How can I reduce the virtual memory required by gccgo compiled executable?

I was able to locate where gccgo is asking for so much memory. It’s in the libgo/go/runtime/malloc.go file in the mallocinit function: // If we fail to allocate, try again with a smaller arena. // This is necessary on Android L where we share a process // with ART, which reserves virtual memory aggressively. // … Read more
