问题
I'm trying to do some semi test driven design, and occasionally when I implement a new feature, it will have an exception somewhere. All gtest tells me is what the exception is, and does not give me any backtrace information.
If I run gdb --args --gtest_catch_exceptions=0, it will stop at the test with the exception but not have any backtrace information. It simply states:
[ RUN ] TESTNAME.test_case
EXCEPTION: exception description[Inferior 1 (process 30528) exited with code 0377]
(gdb) bt
No stack.
回答1:
Use catch throw
gdb command to set special breakpoint before your exception is thrown. When it is hit you can see backtrace as usual by command bt
. See https://sourceware.org/gdb/onlinedocs/gdb/Set-Catchpoints.html.

In a more automatic way, you can add your own listener and then combine the output of failing test-cases by printing additionally the backtrace using How to make backtrace()/backtrace_symbols() print the function names?
