Thanks for the report. This looks the same as #630, no?

[Arfrever]

I am not sure. Backtrace is very similar, but GLog is built as shared library in Gentoo.

[sergiud]

Does disabling TLS help?

[Arfrever]

Do you mean that potential set_target_properties (symbolize_unittest PROPERTIES CXX_VISIBILITY_PRESET default) change in CMakeLists.txt? Or something else?

[sergiud]

I mean configuring glog with -DWITH_TLS=OFF.

[Arfrever]

According to @asarubbo:

• glog 0.5.0 passes tests.
• glog 0.6.0 with set_target_properties (symbolize_unittest PROPERTIES CXX_VISIBILITY_PRESET default) added to CMakeLists.txt still has the same failure in symbolize_unittest:TestWithReturnAddress().
• glog 0.6.0 configured with -DWITH_TLS=OFF passes tests.

However I would prefer to not disable TLS feature.

[sergiud]

Similar to #630 this should no longer be an issue with glog at head.

Please verify and report in case the issue persists.
