plijnzaad / quilt Goto Github PK

@plijnzaad, I'm wondering if there's a license for this software, specifically to determine if it's okay to use this in a commercial context.

Thanks!

Hi Philip,

I noticed from the commit logs that you're aware of Segfaulting on Mac OS X with version 1.2. I did a little digging to see if I could debug this, but the stack trace was not very helpful (at least not to me).

However, I have discovered that I can get the program to run to completion if I get rid of the .quilt-spheres file. The file will fail to be found, will get written out, and then run to completion. If I then immediately try to run it again, it fails. I wonder if some of the code in io.c related to reading in of the .quilt-spheres file is to blame? Will do what I can to confirm if I have time.

Also, great to see that you created a GitHub project for QUILT. Looks like the last time we communicated about QUILT was over 10 years, back in 2011.

Best,
