From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>
Build using Address Sanitizer (asan), Leak Sanitizer (lsan), or
Undefined Behavior Sanitizer (ubsan) by using one of these options for
the configure script:
--enable-asan
--enable-lsan
--enable-ubsan
For each of these to work, the compiler must support the requested
sanitizer and the requisite libraries must be installed (libasan,
liblsan, libubsan).
---
v2: Attempt to fix CI findings
v3: Yet again attempt to fix CI findings, disable running tests with
valgrind if either asan or lsan are enabled are they are likely going
to conflict.
