Test failures on 32-bit platforms with cppcheck 2.19.0

Unfortunately we haven't been able to test 32-bit builds in our CI for a while now. Those tests indeed fail on a 32-bit platform.

Test failures on 32-bit platforms with cppcheck 2.19.0

Hi,

I'm observing three different test failures while trying to upgrade Alpine Linux's cppcheck package from 2.18.3 to 2.19.0. Only the 32-bit platforms (x86, armv7, armhf) are affected.

test/testcondition.cpp:2638(TestCondition::oppositeInnerConditionEmpty)
test/test64bit.cpp:107(Test64BitPortability::functionpar)
test/test64bit.cpp:258(Test64BitPortability::returnIssues)

Full output of the failing assertions is:

[...]/cppcheck/src/cppcheck-2.19.0/test/testcondition.cpp:2638(TestCondition::oppositeInnerConditionEmpty): Assertion failed. 
Expected: 
[test.cpp:1:45] -> [test.cpp:1:60]: (style) Condition 's.empty()' is always false [knownConditionTrueFalse]\n

Could you confirm that those tests are known to pass for 32-bit (musl-based) platforms?

Thanks,
