Neither show segmentation faults when I set LD_PRELOAD='/lib/libncurses.so.6.1' while both are linked to libncursesw. Obviously that does corrupt text output.
Ah, with --as-needed it seems libtinfo linkage is removed whereas it does provide functions that libncurses needs. Calling LD_PRELOAD='/lib/libtinfow.so.6.1' pinfo open and LD_PRELOAD='/lib/libtinfow.so.6.1' ncmpcpp both work fine.
Han Han: Looks like your best bet would be to re-emerge everything that depends on sys-libs/ncurses. Doing that for app-text/pinfo does seem to work. base-system: Generally I don't see another way to resolve this problem: libncurses resolves the external symbols that are needed but (internal) functions that are now part of libtinfo appear to be noops and fail to set up the terminal properly, causing segmentation faults for terminal capabilities.
*** Bug 697776 has been marked as a duplicate of this bug. ***
Yeah, add `app-misc/abook` to this list. Definitely seems like something with ncurses rebuild.
*** Bug 707760 has been marked as a duplicate of this bug. ***
Also app-misc/gtypist, proposed patch in #707760
Also in app-cdr/cdw, however while upstream is correct, the ebuilds add the additional linkage to ncurses instead ncursesw (src_configure). Works after changing it to ncursesw.
Same for ftptop from net-ftp/proftpd (1.3.7_rc3@07/13/20) and sys-libs/ncurses (6.2-r1(0/6)@07/13/20) «Fixed» with LD_PRELOAD='/lib/libtinfow.so.6.2' ftptop
If(!) this is the same thing, it also affects musickube [1] which has an ebuild in Guru [2] and a related patch [3]. The upstream issues are [4] and [5].
