Package: libc6 Version: 2.24-11+deb9u1 Severity: important Dear Maintainer,
1.I've updated the following packages: libc-dev-bin (2.24-11+deb9u1) to 2.24-11+deb9u3 libc6 (2.24-11+deb9u1) to 2.24-11+deb9u3 libc6-dev (2.24-11+deb9u1) to 2.24-11+deb9u3 2.Then I launched WVDIAL ................ root@debian:/home/mydebi# wvdial --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: AT+CGDCONT=1,"IP","xxxxxxxxx" AT+CGDCONT=1,"IP","xxxxxxxxx" OK --> Modem initialized. --> Sending: ATD*99# --> Waiting for carrier. ATD*99# CONNECT 100000000 --> Carrier detected. Starting PPP immediately. --> Starting pppd at Mon Mar 11 18:03:04 2018 --> Pid of pppd: 1616 wvdial: utils/wvtask.cc:303: static int WvTaskMan::yield(int): Assertion `*current_task->stack_magic == WVTASK_MAGIC' failed. Aborted ................ The connection has been established, the internet works but this nasty message :( wvdial: utils/wvtask.cc:303: static int WvTaskMan::yield(int): Assertion `*current_task->stack_magic == WVTASK_MAGIC' failed. Aborted 3.The dependency analysis indicated that the above two files: libc6 and libc6-dev appear as dependencies in libwvstreams4.6-base (my version is: 4.6.1-11). 4.I've tried two different USB modems. To work normally, I returned to version: libc-dev-bin (2.24-11+deb9u1) libc6 (2.24-11+deb9u1) libc6-dev (2.24-11+deb9u1) 5. !!! CONCLUSION !!!. The problem (error) is probably in the updated files: libc6 or libc6-dev or libc-dev-bin, hmmm ??... or in the absence of actualization the libwvstreams4.6-base file (my version is: 4.6.1-11) Debian GNU/Linux 9.4 (stretch) Kernel: Linux 4.9.0-6-amd64 Versions of packages libwvstreams4.6-base (ver. 4.6.1-11) depends: libwvstreams4.6-extras ver. 4.6.1-11 libc6 ver. 2.24-11+deb9u3 (PROBLEM !) 2.24-11+deb9u1 (NO PROBLEM) libgcc1 ver. 1:6.3.0-18+deb9u1 libstdc++6 ver.6.3.0-18+deb9u1 zlib1g ver.1:1.2.8.dfsg-5 -- System Information: Debian Release: 9.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-6-amd64 (SMP w/2 CPU cores) Locale: LANG=pl_PL.UTF-8, LC_CTYPE=pl_PL.UTF-8 (charmap=UTF-8), LANGUAGE=pl_PL.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libc6 depends on: ii libgcc1 1:6.3.0-18+deb9u1 libc6 recommends no packages.
