Hi,
Thanks to AddressSanitizer (ASAN), I found a number of direct leaks
worth fixing. Note that there are probably many indirect leaks left (I
am adding some here), I haven't investigated much yet.
There are still a number of direct leaks remaining, in particular in
the tests, but my libc doesn't give me good backtraces.
In order to easily switch to asan-enabled build, I make use of make
CFLAGS argument, which is why the first patch is also there.
The series is also available for convenience in
https://github.com/elmarco/qemu leak branch.
Marc-André Lureau (37):
build-sys: use an override for CFLAGS filter
