+// dwarfdump-decompression-error.elf-x86-64 is prepared using following
+// source code and invocation:
+// test.cpp:
+// int main() { return 0; }
+//
+// gcc test.cpp -o out -g -Wl,--compress-debug-sections,zlib
+//
+// After that result object was modified manually. One random byte in compressed
+// content of .debug_info section was changed to 0xff. That breaks normal 
+// decompression flow in runtime.
