Hi, I'm trying to use valgrind on ARM. I checkout the SVN version yesterday and cross compile it for my ARM 926EJ (armv5, not sure if the fact that the port seems to be tested on a armv7 may be an issue). I'm using trunk checkout from yesterday. I had to modify the file exp-ptrcheck/h_main.c due __NR_ioperm not defined on the ARM kernel (I added a conditional test for compilation). When I try to run memcheck I got a segfault. I generate a core file and debug the backtrace (attached). Any suggestion on what's going on? I'm willing to help improve valgrind on ARM v5 (if is not supported), but I would need some pointers on what are the v7 specific stuff I may have to take a look at. Thanks for the help Diego. (gdb) core memcheck-arm-li.core warning: core file may not match specified executable file. Core was generated by `valgrind --tool=memcheck gst-launch'. Program terminated with signal 11, Segmentation fault.
