What OS do you have and which version of gdb? The list
command should
list the code around the line where the crash happens, but it doesn't do
it for you.
this is debian jessie with GNU gdb (Debian 7.7.1+dfsg-5) 7.7.1.
Anyhow, you can extract the code around
src/modules/pv/pv_core.c:2243
and send it here, to be sure it is the one you use at the time of
crash.
i built new deb from latest master and re-run the crash. gdb tells:
2238 pv_core.c: No such file or directory.
