** Description changed:
When using the shared libclang_rt.asan-x86_64.so, __asan_default_options
aren't working. Consider the following example:
- $ cat test_asan.c
+ $ cat test_asan.c
const char *__asan_default_options() {
- return "help=1";
+ return "help=1";
}
int main()
I can confirm this. I was actually involved in implementing OMPT support in the
LLVM OpenMP runtime and the startup works by overwriting the weak symbol
ompt_start_tool via LD_PRELOAD. The symbol is there, as seen with
$ objdump -T /usr/lib/x86_64-linux-gnu/libomp.so.5 | grep ompt

Any updates on this?

[x86_64] Kernel panic when building on NFS in VM

That's weird:

Trying linux-image-4.4.0-98-generic next which should be the last known-
good kernel according to the cached packages in /var/cache/apt/archives
- assuming that it's only related to a kernel upgrade...

It's a kernel panic rendering the system unusable, so I can't run any
diagnostic commands.
