Tested simutrans with AddressSanitizer and got error at startup:

Looks like player_day initialized with start value when calc_base_pal_from_night_shift called before activate_player_color or display_set_player_color_scheme which sets player_day.

That is extremely odd, since it works for me (albeit on Windows) and this is unchanged from Standard (I have recently updated to the latest version of simgraph16.cc from Standard). I have also been incorporating other changes from Standard this afternoon - can you re-test with the latest commit?

I update to c20716cafebb2d7f5974bec8051c3b62de544a87 but nothing changed. I suppose Standart affected so.

In what conditions do you get this error? I am not getting any crashes at startup.

It doesn't crash it just reads unknown data outside an array from the global memory what is a error for address sanitizer.

jamespetts

I do not understand that - the backtrace that you posted is of a segmentation fault, which is the name (in Linux) for a program trying to read memory outside the range of memory allocated to that program by the operating system. This will inevitably cause the program to terminate (which is what the SIGSEGV message denotes).

Are you able to test with Standard to see whether this error also occurs there?

Thank you for testing this.

O01eg, since addresssanitizer isn't part of the default options, could you add step-by-step instructions on how you enabled that?

SIGSEGV happens inside sanitizer and doesn' t happen without it.

I'll try to build simutrans standart with sanitizers if it have same error.

I just add `-fsanitize=address -fsanitize=undefined -fPIC -fPIE` into environment variables CFLAGS and CXXFLAGS and `-fsanitize=address -fsanitize=undefined -pie -fPIE` into LDFLAGS.

Thank you - that is very helpful. In the meantime, I will try to see whether I can reproduce this with Dr. Memory.

Edit: I cannot find anything significant running a Visual Studio debug build with Dr. Memory:

I got the same error with Standard version rev d53a6714d3e163513af00505c8e5206f8ed2035a at master branch.

Thank you - that is very helpful. In the meantime, I will try to see whether I can reproduce this with Dr. Memory.

Edit: I cannot find anything significant running a Visual Studio debug build with Dr. Memory:

I can suppose Dr. Memory cann't find UNADDRESSABLE ACCESS in global memory only stack or heap.

jamespetts

Thank you for checking that: that is most helpful. I will move this to the Standard bug reports section, since it can be reproduced in Standard and is not code that I have written or understand.

simgraph16.cc line 1918 doesn't contain code that should be able to crash, unless it is a compiler bug. If you are running an older version that r8184, please state which version. Although it would be better if the error was reported on r8184 or newer.

Dwachs

there was indeed an out-of bound read in line 1955 with player_day = 0xff. should be fixed in r8189.

thanks for the report

Splendid - now also incorporated into Extended where this was originally reported.
