Bug ID: 66524
Summary: Unable to detect InitializationOrderFiasco when
compiled with "g++ -fsanitize=address"
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: critical
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: bhupendra_thosare at persistent dot co.in

Target Milestone: ---
I am trying to run sample program provided in following link using g++ (4.8.2)
to report "initialization-order-fiasco" error.
https://code.google.com/p/address-sanitizer/wiki/InitializationOrderFiasco
However, if we are using g++ it do not report any error for following commands:
ASAN_OPTIONS=check_initialization_order=true ./a.out
export ASAN_OPTIONS=check_initialization_order=1; ./a.out
a.out // It will not work as AddressSanitizer can optionally detect dynamic
initialization order problems.
We are using following script to build and run the sample program:
==================================================================
# For gcc to print line numbers
export ASAN_OPTIONS=symbolize=1
export ASAN_SYMBOLIZER_PATH=/usr/bin/llvm-symbolizer
#export ASAN_OPTIONS=check_initialization_order=1 # NOT WORKING :-/
flags="-fno-omit-frame-pointer -fno-common"
echo "+++++++++++++++++++++++++++++++++++++++++"
echo "++++ Loose init-order checking"
echo "+++++++++++++++++++++++++++++++++++++++++"
rm -f a.out
g++ -fsanitize=address $flags -g a.cc b.cc
echo "**** ASAN_OPTIONS=check_initialization_order=true ./a.out ****"
ASAN_OPTIONS=check_initialization_order=true ./a.out
==================================================================
If we use "clang++" instead of "g++" in above script then it reports
"initialization-order-fiasco" error for same sample program.
Please let us know if I am missing any step OR
"ASAN_OPTIONS=check_initialization_order" is not supported for gcc 4.8.2.
