[cfe-users] marking gtest runs as failed when errors by sanitizers are found

[Alexey Samsonov]

Hi,

You can try either of the following:
a) compile your code with -fno-sanitize-recover=all. Then all UBSan errors
should be fatal.
b) run your executable with setting up the environment variable
UBSAN_OPTIONS=halt_on_error=1
(like this: UBSAN_OPTIONS=halt_on_error=1 ./path/to/your/executable,
setenv() in program will not work).

Let me know if it helps.
