Description
The tests in base64 crate decode_detect_invalid_last_symbol_every_possible_three_symbols use a lot of RAM and doesn't free it while it doesn't happen when compiled with LLVM.

Research direction
Start with the base64 test named decode_detect_invalid_last_symbol_every_possible_three_symbols and reproduce its OOM behavior under the rustc_codegen_gcc backend. Compare the result with LLVM and inspect how the test exercises invalid symbols. Done means the test no longer exhausts memory while retaining the expected decoding behavior.
