The segmentation fault is only caused when the category LC_COLLATE is changed (through LC_COLLTE or LC_ALL). There are no problems with the other categories. I suspect the implementation of `__collate_load_tables_l' in `lib/libc/locale/collate.c'. I'm not sure but maybe there is a memory leak caused by missing `munmap'? https://github.com/freebsd/freebsd/blob/b6fca3ee8065a5cfd3a36abfd7a2663eb5b= fee7d/lib/libc/locale/collate.c#L184 --=20 You are receiving this mail because: You are the assignee for the bug.=
