On my system, I have: $ dpkg -S /usr/lib/gcc/x86_64-linux-gnu/5/libasan.so libgcc-5-dev:amd64: /usr/lib/gcc/x86_64-linux-gnu/5/libasan.so $ dpkg -S /usr/lib/x86_64-linux-gnu/libasan.so.2 libasan2:amd64: /usr/lib/x86_64-linux-gnu/libasan.so.2 > so there's no plain libasan.so.

I think you could try to jhbuild shell into your environment, look at $LD_PRELOAD, prefix it with the path to libasan, and then do "make" or whatever command it intended to execute. If that works, it needs to be made nicer, though. Another option altogether may be to statically link ASan with -static-asan. I haven't tried that yet, however. I also don't know how well it actually works in the particular case of ld_opened libraries that you are describing.

It was for cases when mixing with and without asan built code, if I recall correctly. You should teach jhbuild to add the asan/ubsan first, I'm afraid (or to concatenate the LD_PRELOAD with some shell value, similar to CFLAGS above.
