I won’t post the specific software I’m having trouble with here. This is more like a resource-based question. I know in Stackoverflow you don’t solve problems like this.

My question is, for open-source software (usually on Github), who can I ask for help with runtime error issues when the developers go AWOL.

Just as an example (to give context), I’m getting this error free(): double free detected in tcache 2 in a code I downloaded from Github. Given that this seems to be an allocation issue I tried contacting the developers but they haven’t replied and at this point I really don’t expect them to. My knowledge in C++ is quite basic, so I don’t think I can fix this error myself. Nor I know how to approach it, apart from looking at every single time a vector gets deallocated, and given the code is large and I’m not familiar with it I don’t even know how to tackle this.

Are there any C++ resources/websites out there that could help me find the cause of this error? This software package is quite new, so there isn’t a community I could ask to.

Thanks! And please don’t downvote this post. It could be a relevant question for people needing help with software-specific issues that cannot get answered on Stackoverflow.
