            Bug ID: 496972
           Summary: FreeBSD issues with pure
    Classification: Developer tools
           Product: valgrind
           Version: 3.24 GIT
          Platform: FreeBSD Ports
                OS: FreeBSD
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: memcheck
          Assignee: jsew...@acm.org
          Reporter: pjfl...@wanadoo.fr
  Target Milestone: ---

Recently I tried running a Qt app with memcheck. I got huge numbers of spurious
looking conditional jump errors. I couldn’t tell where they came from - just 2
hex addresses in the call stack. I suspected self modifying code.  --smc
-check=all didn’t help.

Using vgdb there was also no call stack at the error location. When I stepped
out of the asm back into library code it was pre. I’m pretty sure that is some
kind of generated code for regular expression FSAs.
