cppcheck 2.17.0 adds checks that a NULL pointer returned from malloc() and
calloc() is not used.
We do this quite a lot.
I've addressed this by adding functions g_malloc_nofail() and
g_calloc_nofail() which either allocate memory or abort.
functions are now called in places where we are not making these
checks.
Many of these checks are in test programs or example programs.
I've modified the list16 module to handle out-of-memory conditions.
Normally the test runners run in 'forking mode'. When a lot of
messages are logged to stdout, the child process can still be writing
data when the parent writes 'ok' or 'not ok'. This can confuse
the tap-driver.sh process.
These tools shouldn't be delivered to end-users, included in distro
packages. Also the execuable names "memtest" and "tcp_proxy" are too
general to install into sbin dir.
