I've constructed a basic example which crashes GNU APL under OpenBSD; it explains the cause, but the notice may still be valuable:
'1'⎕EA'1÷0' Cannot show function call stack since execinfo.h seems not to exist on this OS (WINDOWs ?). Process apl finished I'm also interested in having some of my programs listed in the GNU APL Community page. Follows are the relevant pages; there's another article, 2017-02-02, but this may be considered too vulgar: http://verisimilitudes.net/2019-08-08 gopher://verisimilitudes.net/12019-08-08 http://verisimilitudes.net/2019-12-06 gopher://verisimilitudes.net/12019-12-06 My relevant code should all be classified as L1 portability, as I strive for portable and so correct APL programs. The programs are all licensed under the AGPLv3. Another reason I send a message here is because I'm having issues debugging my 2020-02-20, which I'd also care to have included once I've finished correcting it. The ⎕TRACE doesn't provide enough information for me and I'm unaware of how to properly use ⎕STOP, managing to crash GNU APL under OpenBSD whilst using it. I'd appreciate help in using these two commands to their fullest, if one is willing to offer it.
