Segfault withlayout layout definition

[levaidaniel]

When configuring a layout, specifying a master_grow value other than 0 results in a segfault. Backtrace inline.

Also, in the manual, it says

layout

The layout keyword after stack_inc is probably rogue. At least the error message spectrwm prints out to the console when it fails to start because of an invalid layout definition doesn't include that (also I can not imagine what would that be).
