FAIL: libmudflap.c++/pass41-frag.cxx (-O3) execution test
All the log entries show "number of nearby objects: 0". Does this mean that it
is
not the test itself that is failing but instead something other than the test -
IE:
GXX is compiling incorrect code or the libraries are incorrectly written.

This is a single-threaded thread-unaware GCC "mudflap" memory-checked binary.
Mudflap is Copyright (C) 2002-2004 Free Software Foundation, Inc.
The mudflap code can be controlled by an environment variable:
$ export MUDFLAP_OPTIONS='<options>'
$ <mudflapped_program>
where <options> is a space-separated list of
any of the following options. Use `-no-OPTION' to disable options.
-mode-nop mudflaps do nothing
-mode-populate mudflaps populate object tree
-mode-check mudflaps check for memory violations [active]
-mode-violate mudflaps always cause violations (diagnostic)
-viol-nop violations do not change program execution [active]
-viol-abort violations cause a call to abort()
-viol-segv violations are promoted to SIGSEGV signals
-viol-gdb violations fork a gdb process attached to current
program
-trace-calls trace calls to mudflap runtime library
-verbose-trace trace internal events within mudflap runtime library
-collect-stats collect statistics on mudflap's operation
-sigusr1-report print report upon SIGUSR1
-internal-checking perform more expensive internal checking
-print-leaks print any memory leaks at program shutdown
-check-initialization detect uninitialized object reads
-verbose-violations print verbose messages when memory violations occur
[active]
-abbreviate abbreviate repetitive listings [active]
-timestamps track object lifetime timestamps [active]
-ignore-reads ignore read accesses - assume okay
-wipe-stack wipe stack objects at unwind
-wipe-heap wipe heap objects at free
-heur-proc-map support /proc/self/map heuristics
-heur-stack-bound enable a simple upper stack bound heuristic
-heur-start-end support _start.._end heuristics
-heur-stdlib register standard library data (argv, errno, stdin,
...) [active]
-free-queue-length=N queue N deferred free() calls before performing them
[4]
-persistent-count=N keep a history of N unregistered regions [100]
-crumple-zone=N surround allocations with crumple zones of N bytes
[32]
-lc-adapt=N adapt mask/shift parameters after N cache misses
[1000003]
-backtrace=N keep an N-level stack trace of each call context [4]
Modified libmudflap operation (seems to show much more problems):
# export MUDFLAP_OPTIONS="-check-initialization"
# ./pass41-frag.exe

Jan, we verified that your patch

caused this regression. Can you take a look? Thanks.

I think component shouldn't be target because it fails on more than one
platform.

Pointer to http://gcc.gnu.org/ml/gcc-patches/2008-07/msg00371.html where Martin
Jambor says he has looked at this bug and says he thinks it is a libmudflap bug
and not actually related to the patch that caused it to start showing up. He
mentions that -heur-proc-map MUDFLAP option makes it go away.
