Description Sami Wagiaalla 2007-11-13 16:02:10 UTC 
the following test are failing for me on f7 x86_64

1) testAllLibrariesGetDetected(frysk.ftrace.TestLtrace)
2) testCallRecorded(frysk.ftrace.TestLtrace)
3) testArgumentsCorrect1(frysk.ftrace.TestLtrace)

Full stack traces:

Comment 1 Petr Machata 2007-11-13 20:12:19 UTC 
The problem is that on x8664, some binaries are mapped non-continually, e.g.:
34c3a00000-34c3a1b000 r-xp 00000000 08:01 3068168 /lib64/ld-2.7.so
34c3c1a000-34c3c1b000 r--p 0001a000 08:01 3068168 /lib64/ld-2.7.so
34c3c1b000-34c3c1c000 rw-p 0001b000 08:01 3068168 /lib64/ld-2.7.so

I'll have to revamp mapping reporter a bit.
