+Subject: [PATCH] Bug fix for data type length judgment.
+
+...
+if (byte_size == sizeof(long)) {
+
+	*type = is_signed ? ARGTYPE_LONG : ARGTYPE_ULONG;
+
+	return true;
+
+}
+...
+
+If ltrace's target command has a dbg package, ltrace will look for the debug file and analyze its contents.
+Ltrace determines the type of analysis result variable. The type of the variable is longlong.
+On 32-bit systems, longlong is 8 and long is 4 (same as in).
+An error occurred because the ltrace code did not process a variable of length 8.
