+
+This test shows non-crashing of generated code for constants with interesting initizers.
+The potential for these to crash is compiler dependent.
+
+There are two cases:
+1. static constants in one compilation unit (tested here)
+2. extern constants across compilation units (tested by libcfa being loadable, specifically
+   the constant declarations in libcfa/src/limits.cfa, which almost every test exercises,
+   including "hello;" but notably, the "limits" test does not exercise it because that test
+   is compile-only)
+
+Crashes that we have obsrved (#182 and build failures September 2020) are because the libcfa
+initialization is writing to a global variable (which the declaring program wants typed as 
+constant), while the compiler has placed this global in a read-only section.
+
+Compiler dependence includes:
+
+                          Case 1           Case 2
+GCC-6  on Ubuntu 16.04    Never crashed    Never crashed
+GCC-8  on both            Has crashed      Never crashed
+GCC-10 on Ubuntu 20.04    Has crashed      Has crashed
+
+For this test case to fail, with most other tests passing, would be a situation only ever
+observed with GCC-8.
