[Pkg-chromium-maint] Bug#777731: chromium-dbg: Incomplete debug symbols

[Paul Menzel]

Package: chromium-dbg
Version: 40.0.2214.91-1
Severity: normal

Dear Debian folks,


Chromium crashed today and I wanted to create a meaningfull backtrace.

        NetworkChangeNo[1138]: segfault at fffffff4 ip b2100217 sp ad6e8c20 error 5 in chromium[b172e000+60bb000]

Wanting to create a meaningful backtrace from the core dump file I
installed chromium-dbg` for the debugging symbols.

        Reading symbols from /usr/lib/chromium/chromium...Reading symbols from /usr/lib/debug/.build-id/4c/a2c2adb2c05798f349d6314650fd76f742609b.debug...Can't read data for section '.debug_info' in file '/usr/lib/debug/.build-id/4c/a2c2adb2c05798f349d6314650fd76f742609b.debug'
        (no debugging symbols found)...done.

        Core was generated by `/usr/lib/chromium/chromium'.
        Program terminated with signal SIGSEGV, Segmentation fault.

        [Messages with symbols unavailable]

So it looks like not all debugging symbols are there.

It’d be great if these could be added.


Thanks,

Paul
