| |
From: Sebastien Buisson <sebastien.buisson@bull.net>
Fix 'program hangs' defects found by Coverity version 6.5.1: Improper use of negative value (NEGATIVE_RETURNS) Variable is passed to a parameter that cannot be negative. Macro compares unsigned to 0 (NO_EFFECT) This comparison is always true. Operands don't affect result (CONSTANT_EXPRESSION_RESULT) Test is always false regardless of the values of its operands. Wrong operator used (CONSTANT_EXPRESSION_RESULT) Test is always true regardless of the values of its operand.
