The bug seems to occur again. It is ok in svn 2009-06-20, but today's svn code
is has problem.
C program is fine, but C++ program crashed. The error message is :
The instruction at "0x0040a7e0 referenced memory at "0x00000046". The memory
could not be "read".
If I change the libgcc_s_sjlj-1.dll to version 2009-06-20, the program works
fine.
the code at "0x0040a7e0" is :
000000000040a7c0 <__ZL15eh_globals_dtorPv>:
