I just tried this with 8.2.2, 8.4.3 and 8.6.1 on Ubuntu 18.04. I don't get any errors with 8.4.3 and 8.6.1 but `showStackTrace` returns `Nothing`. With 8.2.2 I get this compile error: {{{ [1 of 1] Compiling Main ( testdwarf.hs, testdwarf.o ) /tmp/ghc28125_0/ghc_2.s: Assembler messages: /tmp/ghc28125_0/ghc_2.s:1059:0: error: Error: invalid operands (.debug_frame and .note.GNU-stack sections) for `-' | 1059 | .uleb128 1f-.-1 | ^ /tmp/ghc28125_0/ghc_2.s:1133:0: error: Error: invalid operands (.debug_frame and .note.GNU-stack sections) for `-' | 1133 | .uleb128 1f-.-1 | ^ /tmp/ghc28125_0/ghc_2.s:1162:0: error: Error: invalid operands (.debug_frame and .note.GNU-stack sections) for `-' | 1162 | .uleb128 1f-.-1 | ^ /tmp/ghc28125_0/ghc_2.s:1191:0: error: Error: invalid operands (.debug_frame and .note.GNU-stack sections) for `-' | 1191 | .uleb128 1f-.-1 | ^ `gcc' failed in phase `Assembler'.
