[Debian-astro-maintainers] Bug#1119727: astrometry.net: FTBFS: util_wrap.c:36982:3: error: returning 'void *' from a function with return type 'int' makes integer from pointer without a cast [-Wint-conversion]

[Ole Streicher]

Hi Santiago,

I can't reproduce this locally, and to me the origin (util/util.i) looks 
OK. Maybe you can try to re-run this to see if it may have been caused 
by another package?

Best

Ole
