Assert failure on Gtest 1.5 with VS2005+sp1 #307

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1.Compile Gtest1.5 and then run gtest_unittest.exe

What is the expected output? What do you see instead?
In this test case "TEST(HRESULTAssertionTest, EXPECT_HRESULT_SUCCEEDED) 
", Assert failure appeared in isctype.c _chvalidator(-49,8), para -49 cause 
_ASSERTE((unsigned)(c + 1) <= 256) to produce a assert failue. 

What version of Google Test are you using? On what operating system?
winXP + VS2005SP1, Gtest1.5

Please provide any additional information below, such as a code snippet.

below is the call stack:

IsHRESULTSuccess() calls isspace(), which accepts either an unsigned char or 
EOF.  We are giving it a char, which could be signed depending on the compiler 
flags.  We should cast the char to unsigned char before calling isspace().

This should be fixed in trunk r480.
