New build crashes with Segmentation Fault

[flagmaggot]

Using my fork it performs correctly but using your latest fixes (in a separate pull) crashes, I ran using "gdb" and this is what it came back with when it crashes:

Program received signal SIGSEGV, Segmentation fault. 0x00000000080f618e in std::vector<std::unique_ptr<mcpe_viz::BlockInfo, std::default_delete >, std::allocator<std::unique_ptr<mcpe_viz::BlockInfo, std::default_delete > > >::size (this=0x83d2750) at /usr/include/c++/6/bits/stl_vector.h:656 656 { return size_type(this->_M_impl._M_finish - this->_M_impl._M_start); }

Forgot the backtrace:

After some investigation, I find that this line is causing the issue:

https://github.com/Plethora777/mcpe_viz/blob/5d11d70d21405f5ec6def1005117853591a0de27/mcpe_viz.cc#L3248

adding some debugging code, I'm finding that blockid is a negative number (-127, -43, -97 to list a few)

Thanks - will have a look at this

Did you run --html-all or --html-most?

[Plethora777]

Pushed an update - give it a try

[hulmgulm]

It works again for me. Thank you!

[flagmaggot]

Works fine here too. Btw I was using --html-all when the error was occuring.
