Re: gEDA-bug: Bus error in gschem

[Carlos Nieves Ónega <cnieves@xxxxxxxxxx>]

Hi John,
did you changed the colornames in gschem-lightgb, gschem-darkbg, or
whatever scheme you are using?
I think that error could only happen when the colorname length is
greater than 30 characters... a long colorname!.
Anyway, I changed in CVS the x_color_get_name function so it doesn't use
fixed length strings anymore, so the bug should have gone. Please test
it.

Cheers,

Carlos
