A maneira de reproduzir o problema \u00e9 simplesmente recompilar um pacote que usa libtool, e cedo ou tarde isso levar\u00e1 a uma falha bastante estranha.<br \/> Isso significa que, embora o buildd j\u00e1 esteja pronto, realmente me incomoda execut\u00e1-lo, sabendo que ele pode se comportar de maneira desordenada. Quando compilei o conjunto inicial de pacotes para as portas debian (~100 pacotes), tive cerca de 5-10 dessas falhas, o que \u00e9 uma taxa bastante alta: \/&#187;<\/p>\n<\/blockquote>\n<\/li>\n<li> Flavio Cruz <a rel=\"nofollow\" href=\"https:\/\/lists.gnu.org\/archive\/html\/bug-hurd\/2023-11\/msg00033.html\">melhorou o IPC do GNU Mach<\/a>, alterando a ordem dos campos mach_msg_type_t para alinhamento dos bytes msgt_name e msgt_size.
