eXtremeDB compiling error based on vxworks ppcgnu

I still got the compiling errors as follows: 
1, with ppc603gnu compiler and simnt compiler: 
ccppc -DHAS_STDINT=0 -D_VXWORKS=55 -DMCO_CONFIG_OVERRIDE_WCHAR -DMCO_CFG_CHECKLEVEL_1 -DMC 
O_CFG_CHECKLEVEL_2 -DMCO_CFG_CHECKLEVEL_3 -DMCO_CFG_CHECKLEVEL_PIN -DMCO_CONFIG_OVERRIDE_C 
HECKLEVEL -DMCO_DEBUG_DISK_CACHE -DMCO_CFG_USE_DIRECT_POINTERS -I.. -I..\..\..\include -I. 
.\..\..\target\include -g -mcpu=603 -mstrict-align -ansi -fno-builtin -I. -IC:\vx55t22\tar

make: *** [utils.o] Error 0x1 

The error is solved by contacting windriver engineer and updating the ppcgnu and simntgnu. 

Besides,

Indeed compiling with -g -O0 the compiler crash.

But compiling with optimisation and debug -g -O2 the build working without any problem. Please let me know if you've any problem compiling with optimisation?
