find seems to hang on bigger areas

find seems to hang on bigger areas

[Phil Phil via Gdb]

Greetings,

I try to search a relatively large memory area in gdb, something like this:

find /g  0x7f98f0b000, 0x7f99106000, 0x7f955c9390

GDB 11.1 Target: Aarch64 Host: x64

It doesn't finish even after hours. Can there anything be done?

Regards

Is this remote debugging by any chance?

No, it's the same post mortem coredump analysis from my last post. Aarch64 core on an x64 system.

It's only searching 2 Mb, so personally I would suspect a gdb bug of some kind.

If you can reproduce it with a simple test program (like allocate 2 Mb
and fill it, etc), please file a bug.

thanks,
