Segmentation Fault

[ghost]

When I try to run st from another temrinal (in this case, Konsole because I'm running Kubuntu 18) the program does not launch and instead my terminal returns

Segmentation fault (core dumped)

GNU Debugger shows the following outpt

Starting program: /usr/local/bin/st

I've got similar error:

free(): invalid next size (normal)
Aborted (core dumped)

The problem is that the defaultbg value is set to 256, but there is no value for 256 in the colorname array.
There are two easy ways to fix this by editing the config.h file:

Option 1:
Assign a valid value to defaultbg in line 117. change unsigned int defaultbg = 256; to unsigned int defaultbg = 16; (16 would produce a black background color. You can choose a different color from the colorname array. Any number from 0 to 18 should work.)
Option 2:
Add back [255] = 0, before the "more colors can be added.." comment in line 105.

@JohnnyVim thanks. That solved the issue. What i did exactly was changing the value on line 117 to 0.

Worth to note that I expected to get black background because 0 refer to black, instead I get solarized theme background color. Not that I complained, by the way.

Sorry for not getting on this issue earlier, but it looks like you guys had converged on a fix. I've actually switched the background color to 0 now so this particular problem shouldn't be a problem on any other systems.
