[Bug uprobes/24117] System crashes when probing a shared library


https://sourceware.org/bugzilla/show_bug.cgi?id=24117

--- Comment #3 from Serhei Makarov <me at serhei dot io> ---
I took a look at the stap-report but the section containing kernel config did
not generate properly. Can you please also send your
/lib/modules/4.14.24/build/.config?

> So, instead, I tried to probe the libc.so.6 as below but unfortunately got the same result.

That's helpful to know, since it means your custom library isn't needed to
reproduce. Thus far, I have not seen a kernel crash with the example you sent.
My guess is that the kernel you are using has a different CONFIG from mine, or
even some custom patches.

However, I do see a segmentation fault when probing a 32-bit program on my
64-bit system (since /lib/libc.so.6 on my system is 32-bit), which is
definitely a bug (though not the same as the result you're seeing). Is the
program/library you are probing 32-bit on a 64-bit system as well?
