After compiling with gcc (see #470 and #473), I can no longer run the program.

For demo scenario_1_corridor:

$ jpscore corridor_ini.xml

I get without log-file: INFO: Loading and parsing the project file <corridor_ini.xml>Segmentation fault: 11

Interesting!

When compiled with AppleClang

I can confirm that.

~~The q.parent_path() is empty when using boost. Then trying to call fs::absolute on an empty paths causes the SegFault.~~ Edit: The previous assumption was wrong. Even if q.parent_path() is empty fs::absolute returns a valid path when using Clang.

schroedtert commented 5 years ago

The error is maybe caused, when boost is not compiled with the same flags as JPScore. If I remember correctly @Ozaq mentioned something similar in an other issue/PR.

To understand what happened it is very helpful to have a stack trace of the call that triggered the crash. Could you enable coredumps on your machine (https://stackoverflow.com/questions/9412156/how-to-generate-core-dumps-in-mac-os-x) and add the stack traces to this issue?

Once you have coredumps enabled you can open the dump with lldb -c <corefle> when attached you call bt (for backtrace) and paste the stacktrace.

Sorry for the late reply. Here are the results of the core dump:

@schroedtert didn't we fix this?

chraibi commented 4 years ago

@schroedtert do we still have this problem?

gjaeger commented 4 years ago

The described problem with gcc persists. I am currently compiling with AppleClang only.

Ozaq commented 4 years ago

@zeroset I think we can close this

chraibi commented 4 years ago

I think we can close this.
