Hi,

I checked this testcode against gilbc 2.3, 2.5 and 2.7

Please check the below o/p

$ gcc -g -static -L /home/halesh/glibc-2.5/usr/lib abort_t.c 
Aborted

$ gcc -g -static -L /home/halesh/glibc-2.7/usr/lib abort_t.c
Segmentation fault

$ gcc -g static abort_t.c  <- glibc-2.3
Aborted

When i went still more deep..

There is difference in raise.c, is it old code in 2.7?
