Maybe you need to give an argument to strace to have them ? A possible cause could be the page size: as I understand, mips have different page size setup. If your valgrind has been compiled with a pagesize not matching your kernel/setup, then maybe Valgrind might ask wrongly aligned mmap requests, giving then this EINVAL You could then configure/compile valgrind, specifying the correct page size e.g. use the below configure option: --with-pagesize= override detected page size (4, 16 or 64) Philippe ------------------------------------------------------------------------------ BPM Camp - Free Virtual Workshop May 6th at 10am PDT/1PM EDT Develop your own process in accordance with the BPMN 2 standard Learn Process modeling best practices with Bonita BPM through live exercises http://www.bonitasoft.com/be-part-of-it/events/bpm-camp-virtual- event?utm_ source=Sourceforge_BPM_Camp_5_6_15&utm_medium=email&utm_campaign=VA_SF _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
