Message-ID: <b401d2531001060724r4a06401fx9cc8a5dbf24518d3@mail.gmail.com> (raw)

While checking one of big shared objects I found kernel getting
unhappy and sending SIGKILL. File was 282M libwebkit-1.0.so.2.8.1 from
webkit project. (Can be obtained from
and extracted via rpm2cpio, file is libwebkit-1.0.so.2.8.1.debug)

Subject: [PATCH] dwarf_loader.c: Fixed leaked bogon

Freed chunks of memory left by obstack. It went beyond kernels
expectation for libwebkit-1.0.so.2.debug (from
libwebkit-1.0.so.2.8.1.debug) file and so that it had to send SIGKILL.
