Summary0005271: Segmentation Fault when Embarking in PRINT_MODE:TEXT
DescriptionI play DF in text mode on my VPS. 0.31.25 worked without issue.

I can get into Adventure Mode without a problem, but no matter where I embark, I get a Segmentation Fault as soon as you initiate a proper embark from the setup screen.

I'm having trouble reproducing this. Can you run it with 'ulimit -c unlimited' and send me the core file?

I have experienced the same issue on Debian linux in version 0.34.11. The steps I followed are as follows:

1. Start the game. The game's maximum width and height in characters was small.
2. Once the opening animations finished I would resize my terminal,
and DF would resize to a larger size.
3. Choose "Start Playing", Choose "Dwarf Fortress"
4. Select starting location
5. Choose embark and "Play Now!"
6. Game would core

I have a core file that I can make available (I don't seem to be able to upload to issues opened by other users). Here is the backtrace:

Program terminated with signal 11, Segmentation fault.

Backtrace stopped: previous frame inner to this frame (corrupt stack?)

I also have found a workaround which will help pinpoint the issue. What seems to work is to not resize the terminal at all in step 2. Once the normal game screen appears with the wagon and dwarves, resizing the terminal works. I think on embark the game was assuming the terminal was still the smaller size or something. The core is occurring somewhere below strcat(): 0000004 0xb70d6dc7 in strcat() from /lib/i686/cmov/libc.so.6
