I tried to debug it, the first segfault is at https://sources.debian.org/src/yforth/0.2.1-1/search.c/#L84 and is caused by "_align();" at https://sources.debian.org/src/yforth/0.2.1-1/search.c/#L81 which completely changed the address and so it now tried to set NULL to an invalid location. I stopped after seeing there are many such macros like "_align()" which are modifying the pointers and imho, it will be a nightmare to fix it. -- Regards Sudip

I haven't had reason to use yforth in many years, (the package was last updated on 11 October 2012), so I hadn't noticed! My guess is that this is a simple 64-bit system incompatibility, as a quick rebuild of the package on my current 64-bit laptop yields a large number of warnings about casts of pointer from integer of different size... Honestly, I'm not sure this is worth fixing? The upstream site has disappeared entirely. If someone wants to step through the source and fix all the cast issues, I'd be happy to have a patch. But given the availability of gforth and pforth in Debian, just removing yforth from Debian might be the best plan. Bdale signature.asc Description: PGP signature
