can you run
then rerun penumbra
when it "segfaults" again a "core dump" will be generated in the penumbra directory
(core.1332)
The number in the filename will be different for you.
run the following
gdb ./penumbra.bin core.1332
once gdb is started type the following in gdb
Then copy the output (it will be paged so you will have to copy each page of the output)
and attach the output to a new post on this thread.
Do note, that Intel graphics cards are not supported by Penumbra and will probably not work at all.
