Why does Google Test not print a stack trace or file name?

问题

When I use Google Test and Google Mock, with diagnostic level set to "info", I get messages like this:

Uninteresting mock function call - taking default action specified at:
src/pkgtest/test_Foo.cpp:216:
    Function call: GetBar()
          Returns: 4-byte object <00-00 00-00>
Stack trace:

Uninteresting mock function call - taking default action specified at:
src/pkgtest/test_Foo.cpp:126:
    Function call: GetBaz()
          Returns: {}
Stack trace:
unknown file: Failure
C++ exception with description "Uninteresting mock function call - returning default value.
    Function call: CreateGrille(@0x7fff6a557050 { 16-byte object <80-D8 BB-01 00-00 00-00 70-D8 BB-01 00-00 00-00> })
    The mock function has no default action set, and its return type has no default value set." thrown in the test body.

I cannot find anything on the internet about why Google Test/Mock won't print a stack trace, or claims "unknown file". What do I need to do to teach it how to properly dump a stack trace?

(I'm on Linux using g++ 4.9, if that makes a difference.)

According to Samuel Benzaquen:

gTest doesn't include a stack unwinder. You have to provide your own. You can do this in include/gtest/internal/custom/gtest.h by defining the GTEST_OS_STACK_TRACE_GETTER_ macro to point an implementation of OsStackTraceGetterInterface.
