clang34, 35, 36 fails to pass unit tests with C++03

[pshahid]

Hi, I'm getting an error with the signalhandler_unittest with glog 0.3.4 and C++03 with the recent llvm family of compilers.

This is being run on fedora 20, on clang 34, 35, and 36. The following output is from clang35 and 36.

./demangle_unittest  # force to create lt-demangle_unittest
Passed 3 tests

PASS
./src/demangle_unittest.sh
PASS
./signalhandler_unittest  # force to create lt-signalhandler_unittest
OK

'SIGFPE' should appear in the output

The following output is from clang34 on the same system.

Unfortunately I couldn't find test-suite.log to get any error messages out of it. It didn't appear to be created in any of the subdirs from glog-0.3.4.

I should mention that if I skip the SIGFPE unittest in src while using clang35 or clang36 then I still get a failed unit test for src/symbolize_unittest.

The output is:

Test case TestWithPCInsideNonInlineFunction passed.
Test case TestWithReturnAddress passed.
Check failed: streq("static_func", TrySymbolize((void *)(&static_func)))

hey folks! is there any update about that ? I have the same issue here using glog 0.3.5

The test failure is probably due to configure not finding pthread on your systems. The test code is a no-op when pthread was not found:

glog/src/signalhandler_unittest.cc
