// Look for use of expressions with side-effects inside of debug logs.

// This script detects expressions like ++E, --E, E++, and E-- inside of
|
||
|
|
// calls to log_debug().
|
||
|
|
//
|
||
|
|
// The log_debug() macro exits early if debug logging is not enabled,
|
||
|
|
// potentially causing problems if its arguments have side-effects.
