11083	tools/build/src/tools/sun.jam needs additional  -W0,-abiopt=mangle6 for C++ compilations	Sergey.Sprogis@…	Vladimir Prus	"1. Description of the failure
 
Several  tests inside libs/icl/test directory fail with Oracle Studio 12.4 C++ compiler on Solaris producing error message similar to what  one of those tests: libs/icl/test/fastest_interval_set_infix.cpp produces:

2. Cause of the failure.
 
This is a name-mangling compiler bug that compiler developers can't fix without breaking compatibility.
The bug exists on Solaris/Sparc, and on Solaris x86 with -m32.
The bug does not exist on Linux, or on Solaris x86 with -m64, because the bug was discovered before those platforms were supported.
The workaround is to compile with -W0,-abiopt=mangle6, which is the default for the systems were the code works. When you use this option, you must recompile all C++ code and use the option everywhere.

3. Possible Solution.
 
To replace one line inside tools/build/src/tools/sun.jam inside  actions compile.c++ subroutine
by adding  -W0,-abiopt=mangle6 option into compilation instruction. Specifically, replace:

    ""$(CONFIG_COMMAND)"" $(OPTIONS) -D$(DEFINES) -I""$(INCLUDES)"" -c -o ""$(<)"" ""$(>)""

with 

    ""$(CONFIG_COMMAND)"" $(OPTIONS) -D$(DEFINES) -I""$(INCLUDES)""  -W0,-abiopt=mangle6 -c -o ""$(<)"" ""$(>)""
