String question crash

[red-kangaroo]

A string question history was introduced in e91cdad and it seems that both crashes reported here are caused by a string question seg fault.

demangled (c++filt) from:

./Main/ivan(globalerrorhandler::DumpStackTraceToStdErr(int)+0x34)[0x55d9d911a792]
./Main/ivan(CrashHandler(int)+0x15)[0x55d9d90ab870]

./Main/ivan(iosystem::StringQuestion(festring&, festring const&, v2, int, unsigned long, unsigned long, bool, bool, bool (*)(int, festring&))+0x222)[0x55d9d911c1e6]

./Main/ivan(_start+0x2a)[0x55d9d8e8cada]

I think it happens at

truth game::Init(cfestring& loadBaseName)
...
      if(iosystem::StringQuestion(PlayerName, CONST_S("What is your name? (1-20 letters)"),
                                  v2(30, 46), WHITE, 1, 20, true, true) == ABORTED

he said ubuntu 18

the other from the screenshot apparently happens when trying to change the player's name I guess. he said linuxmint 20.3

both crashes happens at the rewind.

int iosystem::StringQuestion(festring& Input,
...
  festring fsHistFile = festring()+GetUserDataDir()+".QuestionHistory_"+fsFixTopicToFileName+".txt";
  DBG1(fsHistFile.CStr());
  FILE *fl = fopen(fsHistFile.CStr(), "a+");
  rewind(fl);

It would be good to know the value of fsHistFile, and if that file is being really created.
I think rewind is unnecessary in case the file have been just created also.
May be the fopen mode "a+" could be a better option to prevent this crash?

[AquariusPower]

I think it could catch the error and retry a few times before aborting.
Most certainly their filesystems are not full neither readonly.

But... this could be a user write permission problem!
I think we could check for user write permissions on the specified path?

btw: https://www.cplusplus.com/reference/cstdio/fopen/

ubuntu 18.04
game seems to run, but i was using 0.58 before without issues and overwrote my directories

possibly since the game wants to use the folder /usr/local/share/ivan
i own this folder so lets sudo chown -R root:root /usr/local/share/ivan
game runs fine

sorry. nothing to see here...

[SSUPII]

Can anyone check if this issue is still happening on their end? We might close this issue if it is.

The crash is happening for me on 059, but it is not present in master.
