Description Esteve Varela Colominas 2023-05-02 19:27:43 UTC
Currently, building dev-lang/jimtcl when it's already installed breaks, with a "*** buffer overflow detected ***: terminated" message.

This is fixed in 0.82[1], but in order to prevent this issue and similar potential issues in the future, I'd consider *always* building a bootstrap shell.

The file "autosetup/autosetup-find-tclsh", first looks for "./jimsh0" before trying the installed shell, and regular tclsh. If it finds none of them, it builds jimsh0 using "$CC_FOR_BUILD -o jimsh0 autosetup/jimsh0.c".

I think replicating this build command in the ebuild would be simple enough.

Perhaps a USE=system-bootstrap instead. But really, this was kind of a specific issue which needed resolving, no?

I think having different behavior between a clean install and an upgrade leads to hard to detect bugs like this one. Anyway, I'll be sending a PR in a bit.
