Re: [libgadu-devel] Segmentation fault w teście resolvera (było: Re: libgadu 1.12.0-rc1)

[Tomasz Wasilczyk]

Niestety, nie jestem w stanie zreprodukować tego błędu.

System mam zainstalowany z: http://ftp.pbone.net/pub/fedora/linux/development/rawhide/i386/os/images/boot.iso

Jedyna opcja do configure: "--with-pthread=yes".

$uname -a


make przechodzi bez warningów, make check 100% na zielono.

Być może pomogło by więcej logów (z configure, config.h).

Pozdrawiam,
Tomek

Próbuję właśnie zbudować nową paczkę dla Fedory i o ile na F20 buduje
się bez problemów i testy przechodzi, o tyle na wersji rozwojowej
(Rawhide/F21) dostaję segmentation fault przy teście resolvera (ale
tylko na x86_32):

$ make check
