running qq.exe from issue #337 we see:
SYSLOG_WARNING: CURIOSITY : !opnd_is_far_memory_reference(op) in file D:\derek\dr\git\src\core\x86\mangle.c line 4283
SYSLOG_WARNING: CURIOSITY : !opnd_is_far_memory_reference(op) in file D:\derek\dr\git\src\core\x86\mangle.c line 4283
the code just has a FIXME there

Contributor guide
Research direction
Start with src/core/x86/mangle.c around line 4283 and reproduce the SYSLOG_WARNING reported when running qq.exe from issue #337. Trace how far memory references reach this FIXME and use the existing sandboxing behavior as the reference for determining when the warning is resolved.
