Description John Reiser 2009-08-26 19:02:57 UTC
Description of problem: When run on (64-bit) x86_64, then strace for execve() of a (32-bit) i686 process prints just the address when an argv string or environment variable resides above 0xfffffffffff00000.  This happens even in -v mode (verbose), and makes strace much less useful.


Version-Release number of selected component (if applicable):
strace-4.5.18-3.fc12.x86_64


How reproducible: every time


Steps to Reproduce on x86_64 (64-bit):
1. yum install wine
2. wine Notepad  ## starts some background processes
3. File > Exit   ## terminate first Notepad
4. strace -v -f -o strace.out -e trace=execve wine Notepad
5. File > Exit   ## terminate second Notepad
 
Actual results: File strace.out contains the strings for the first execve, but just the addresses for most of the other execve.  Example:
----- first execve
2290  execve("/usr/bin/wine", ["wine", "Notepad"], ["ORBIT_SOCKETDIR=/tmp/orbit-jreis"..., "HOSTNAME=f12a64.local", "IMSETTINGS_INTEGRATE_DESKTOP=yes"..., {{snip}}
-----

----- second execve
2290  execve("/usr/bin/../lib/../bin/wine-preloader", ["/usr/bin/../lib/../bin/wine-prel"..., "/usr/bin/../lib/../bin/wine", 0xfffffffffff9a5f6], [0xfffffffffff9a5fe, 0xfffffffffff9a621, 0xfffffffffff9a637, {{snip}}
-----


Expected results: Arguments and environment variables to execve are printed as strings in every case.
