[xpressive] I got a crash in after i upgrade from 1.44 to 1.74

Boost - Users mailing list

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?

 

Best regards
