To use pass -DCMAKE_BUILD_TYPE=Debug or Asan -DCOVERAGE=ON and build as
usual, then do ninja lcov-initialize && ninja check && ninja
lcov-collect. The result will be a directory, <Builddir>/Coverage
containing lcov tracefiles, including an aggregate file gnucash.info
which you can use for further processing. It will also report an overall summary.
Note that only C/C++ files are included.
There's one more target, lcov-generate-html, that you can run after
lcov-collect. It will generate a simple website in
<Builddir>/Coverage-HTML showing coverage by source directory (the
directories in <Builddir> have coverage for generated files). Each
directory path is a clickable link to a page that shows coverage for
each source file; the filenames link to a page for each showing which
lines have been exercised.
Every test was rebuilding it except for gnc-backend-xml.cpp from
scratch, no point in that plus the Address Sanitizer needs the
definition of GncBackendXml.
xaccSplitComputeCapGains creates gains_split pointers in both the Cap Gains Split and its Income split to the original split, but the original's gains_split pointer can point to only one of them, the Cap Gains split. When the original split is freed both the Cap Gains split's and its Income split need their gains_split pointers NULLed or when it's the Income split's turn to be freed it will try to deref the dangling pointer.
Add new test files that are written with the latest version of GnuCash.
Test loading them, saving to compressed files, loading those compressed
files and writing to an uncompressed file. At every stage check it matches
the canonical version.

Return a gnc_numeric instead of allocations that every caller has to free.
This makes it easier to fix the use after free in the unit test function
equals_node_val_vs_split_internal() where the expression in the return
statement wants to use the allocated gnc_numeric.
81b9a02235 changed the behaviour of the
"success" variable that's used for the return value, so now the value is
being repeatedly overwritten instead of being combined with the result of
the next call.
Restore the original behaviour of setting success to false on failure.

Refactor try_gz_open to return a std::pair<FILE*, thread>. That removes
the need for the threads hash-table and wait_for_gzip().
The cause of the gcc12 error was that we were using the thread's pipe's
FILE* as the key to the hash-table and had to close it before calling
wait_for_gzip(file) to remove the thread from the hash-table. gcc12
considers that a use-after-free. It happens to be wrong, but removing the
need for it results in a cleaner implementation as well as silencing the
warning.
