<pre>clang version:
$ clang --version
clang version 6.0.1 (tags/RELEASE_601/final)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /opt/clang/bin
source file : Doug Lea's malloc
<a href="ftp://g.oswego.edu/pub/misc/malloc.c">ftp://g.oswego.edu/pub/misc/malloc.c</a>
command line:
$ ls -hs
total 220K
220K malloc.c
$ ulimit -m -v
max memory size (kbytes, -m) 4096000
virtual memory (kbytes, -v) 4096000
$ clang-format malloc.c
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
terminate called recursively
Aborted (core dumped)
If not constrained to 4 GB via ulimit, formatter claims all available memory
and my system becomes totally unusable.</pre>
