[GRASS-dev] segmentation fault with temporal commands

[Veronica Andreo]

Hi devs,

I get "segmentation fault" when running temporal commands, i.e., t.list,
t.info, t.create, t.register (haven't tested them all). However, the
command works as expected. It's just that I get the message "Segmentation
fault (core dumped)" whenever I run a temporal command. I use grass trunk
r73007 in Fedora 28.

Here I paste the final part of the strace output (dunno if that's the part
useful):

strace t.info LST_Day_monthly
