Closes #324

[onqtam]

Hi - thanks for this fix! Can you confirm that doctest continues to capture correctly the crash from code such as int* p = 0; *p = 1; if there isn't a __try section in the test case?

I don't think the changes made to .gitignore should be part of this PR (especially adding the *.cmake wildcard) - making an out-of-source build should be preferred.

Yes, in the case you mention, a SIGSEGV continues to be caught and reported by doctest as it was before the fix.

I can revert the changes to .gitignore. For out-of-source builds, what parameters are you running CMake with to build out-of-source. I'd recommend adding a building guide to CONTRIBUTING.md, and include info about how to build, run tests, add tests, etc. :)

About the out-of-source builds - I usually make a build directory within the doctest directory and call cmake from there like this: cmake .. - standard CMake practice - that build directory already has an entry in the .gitignore, but it can be outside of the doctest folder as well - all you need to do is pass the path the root of the doctest repository do CMake. Perhaps I should indeed add some info in CONTRIBUTING.md :)

I'm merging this. Thanks!
