This is Robert Sebastian Herlim.
We are currently working on a new fuzz testing feature, and we found crashes in tic.
For ease of maintenance, I'll send the crash one-by-one by email.
[Step to Reproduce]
We configured ncurses with `CXXFLAGS="-g -O0" ./configure`, and run tic using
- ./tic -t <attached_file> -G -C -a -RBSD -RSVr1 -RHP -c -v5
[Environment]
- OS: Ubuntu 18.04.4 LTS
- Compiler: gcc 7.5.0
- ncurses version: 6.2 (
https://ftp.gnu.org/pub/gnu/ncurses/ncurses-6.2.tar.gz)
[Additional Context]
I also attached the stack trace of the crash.
```
