I'm hoping someone else has seen this issue and is able to help me. I have
search all over the internet for a solution and haven't been able to find
one. I am trying to run Valgrind on armv7 architecture, and after compiling
Valgrind and getting it onto the target I am able to run Valgrind
successfully on 'ls -l' but when I run Valgrind on my executable it starts
and then always fails after printing out this error:
==2333== Unsupported clone() flags: 0x800600
==2333==
==2333== The only supported clone() uses are:
==2333== - via a threads library (LinuxThreads or NPTL)
==2333== - via the implementation of fork or vfork
==2333==
==2333== Valgrind detected that your program requires
==2333== the following unimplemented functionality:
==2333== Valgrind does not support general clone().
==2333== This may be because the functionality is hard to implement,
==2333== or because no reasonable program would behave this way,
==2333== or because nobody has yet needed it. In any case, let us know at
==2333== www.valgrind.org and/or try to work around the problem, if you can.
==2333==
==2333== Valgrind has to exit now. Sorry. Bye!
