Fwd: crash: longjmp vs -fprofile-arcs

[Dale Johannesen]

OK, let me try a different question:

#include <setjmp.h>
int foo (jmp_buf buf) { longjmp(buf, 1); }

now what? cc -fprofile-arcs lj.c
lj.c: In function `foo':
lj.c:2: internal error: Bus error
Please submit a full bug report, blah blah

It seems the block that calls longjmp has no successors, and the code 
in profile.c
is not expecting that.  Could somebody clarify which code is right?
