Hi,
I followed the instructions as mentioned in,
https://bugs.kde.org/show_bug.cgi?id=276897#c0<valgrind-users@lists.sourceforge.net>
to patch Valgrind 3.7.0 for armv5te and generated a build. I see that the
memcheck keeps crashing, the moment I execute valgrind. With help of gdb I
saw the instructions as below. Has anyone seen similar problem or am I
missing anything? Please help!
*(gdb) display /5i $pc
1: x/5i $pc

PS: Please let me know if this mail has to be posted to valgrind-dev-list
as well.
