I started to convert some sprintf() to snprintf(), but I still have 824 cases to go... Ideally, all should be converted to std::string. Will be some job for my retirement ;-)

We have observed the same issue. Did the CodeCogs api change? 

Thanks for the help.

Hi!

I am not sure if this is a know issue: it seems that the equation editor does not work anymore. Is there any fix or alternative method to type latex formula in the log? 

Thank you!

Does this issue occur only on Ubuntu systems? as I've experienced the same on my Raspberry Pi 5 running Ubuntu too ...

A statement like "core dumped" does not help much. Same with valgrind memory leaks. I need a full strack trace with all parameters when the segment violation occurs. The easiest is when you run elogd vom inside gdb, and once you get the signal, do a "where" to see th full stack trace.

As you can see from this forum, there is absolutely no crash when you upload any file, so it must have to do with your config file or anything whcih is special in yoru environment. We have to find what this is so that I can reproduce it here.
