Hi Boost Users
I met a crash in following code after I upgrade from 1.44 to 1.74,
When I used "-O1 -DNDEBUG" to compile, it will crash.
But when I used "-O1" or "-DNDEBUG" or "-O0 -DNDEBUG", it will not crash.
In 1.44, all of them are ok.
My GCC version is 4.1.2 and test in redhat-AS 4 32 bit.

Can you help to check this problem?
