Hi, i'm trying to integrate BURS-based code generator into GCC-4.1.1. I modified corresponding files, print-rtl.c and final.c and my burs-based codegenrator is working fine. But when i'm trying to build compiler proper, its giving segmentation fault. I'm successful with GCC-4.0.0. error message: ../../gcc-4.1.1/gcc/crtstuff.c: In function ?__do_global_dtors_aux?: ../../gcc-4.1.1/gcc/crtstuff.c:301: internal compiler error: Segmentation fault what is this crtstuff? I'm new to this gcc. I need some information regarding this error. can anybody help? Thanks in advance -- Bhaskar G. Reddy, Graduate Student, Department of CSE, IIT Bombay
