Hi Tom.

As you may have noticed, your patch below caused regressions in the libstdc++ testsuite on aarch64: FAIL: libstdc++-prettyprinters/debug.cc print redirected FAIL: libstdc++-prettyprinters/simple.cc print redirected FAIL: libstdc++-prettyprinters/simple11.cc print redirected

For instance, the log contains: $24 = Traceback (most recent call last): File "/home/tcwg-buildslave/workspace/tcwg_gnu_5/abe/snapshots/gcc.git~master/libstdc++-v3/testsuite/../python/libstdcxx/v6/printers.py", line 2279, in to_string got: $24 = Traceback (most recent call last): FAIL: libstdc++-prettyprinters/debug.cc print redirected

Do you know if this is a problem in GDB, or if the testcase needs an adjustment like recently for another one?

Thanks,

Christophe
