demonstration and further details
LeakSanitizer may fail to catch leaked memory based on stack layout.
While I did not perform any extensive research, I did verify that stack layout
is the only changing factor in my compiled binaries by disassembly comparison.
I did not verify whether the underlying issue can cause other problems than the
one described by this report.
Please find attached a C program with comments about the verified environments
and different ways to reproduce.</pre>
