Package: wget Version: 1.19.2-1 Severity: normal Usertags: crash Control: affects -1 + debian-goodies
When I run `dman interfaces` I get a core dump from wget. Here is some discussion from #debian-devel about the issue: <pabs> anyone else running buster/sid get a core dump from wget when running `dman interfaces`? <kilobyte> pabs: in wget sources, the crash is at src/http.c:3715 -- "type" is Content-Type or 0 if there's no such header <pabs> kilobyte: that matches my backtrace, thanks for confirming <kilobyte> pabs: ｢wget -vd -O /dev/null https://dyn.manpages.debian.org/sid/interfaces.5.en.gz｣ confirms there's indeed Content-Encoding: gzip but no Content-Type <kilobyte> pabs: and the fix is obvious Here is some debugging output from gdb and wget: $ gdb -batch -n -ex 'set pagination off' -ex run -ex bt -ex 'thread apply all bt full' --args wget -vd -O /dev/null https://dyn.manpages.debian.org/sid/interfaces.5.en.gz [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
