Upstream said: You can avoid it easily by declaring the destructor correctly or if you forgot the return type in the declaration of a method, add it in. Deleting the appropriate line will also work - note that it is currently being ignored! This seg fault is fixed in trunk for swig-2.0.8, rev 13128. Patch backported to swig-2.0.7-r1 in the lisp overlay. The lcms-1.19 build.log now shows: lcms.i:196: Warning 521: Illegal destructor name COLORW::~COLORB(). Ignored.
Reopening as swig-2.0.7 is now in tree and stable lcms-1.19 won't build for ~arch people. A fix is available in the lisp overlay : http://git.overlays.gentoo.org/gitweb/?p=proj/lisp.git;a=commit;h=76ecbb30433d06622c0def9f6e61d2a7b8764e17
Created attachment 318008 [details, diff] Upstream fix Extracted from rev 14128 http://swig.svn.sourceforge.net/viewvc/swig?view=revision&revision=13128
Fixed in CVS.
