This command does not output the call stack and must be terminated manually using Ctrl+C.

On openEuler 22.03 (LTS-SP4) running on a Kunpeng-920 core (AArch64)

Adding the -debug option produces the following output, with the main error message being:

<Application /usr/bin/ls (3706039). Internal Error: DynamoRIO debug check failure: /home/runner/work/dynamorio/dynamorio/core/unix/memcache.c:225 ALIGNED(start, PAGE_SIZE)

Does anyone know what the problem is?

Hello,

Thanks for reaching out. Based on first impression, this looks like a bug. Could you please file a bug report at https://github.com/DynamoRIO/dynamorio/issues? Remember to include all details requested by the template, and perhaps also the libc version.
