Hi Markus,
It looks like you sent patch for review to the gdb alias.
I am only in binutils@sourceware.org.
See my comments below.

Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]
I ran gprofng.display/display.exp on Fedora 36 x86-64 and I got

     UNSUPPORTED: jsynprog

It is expected. You built gprofng without java profiling support.


     ERROR: comparison of results in mttest failed
     UNRESOLVED: mttest
     ERROR: comparison of results in mttest failed

     UNRESOLVED: mttest
     PASS: synprog
     PASS: synprog


Usually, when synprog passes and mttest fails, it means that 
pthread_create interposition is broken in libgp-collector.so.
In any case, it is not result of your patch.
I never run gprofng on Fedora 36.
Please create a bug against gprofng and describe how you configure your 
build.



with and without this patch.

I suggest to just remove TprintfT. This debug output is currently not 
used by anyone.

Thanks for fixing this, and please check it in.
