[Lldb-commits] [PATCH] D35734: Don't allow LLDB to try and parse .debug_types

I believe a crash looks like:

  #include <stdio.h>
  
  int main(int argc, const char **argv) {
    typedef enum FooTag {
      Bar,
      Baz
    } Foo;
    Foo foo = Bar;
    printf("foo = %i\n", foo);
    return 0; // Break here and "frame variable"
  }

The enum gets put into a type unit, and then we get an assertion when trying to get the byte size for an integer whose byte size is zero. -fdebug-types-section doesn't work on Mac as the flag is just ignored. Also, can we just assume "-fdebug-types-section" is available for any compiler that we run the LLDB test suite with? I am guessing that isn't the case so we should limit any test case to GCC or clang.

Can you compile the above code snippet and see if it crashes on linux?
