> Why are you running wo_prof_mult_field_peeling.c with profiling?

My best guess is because I have reused some previous command line(s) with it
(from gcc.dg/struct/w_prof_global_array.c for instance) without thinking about
it. 

Anyway, I have run all the tests in  gcc.dg/struct failing with 
-m64 with -O3 -fipa-struct-reorg -fwhole-program -combine -fipa-type-escape
-m64 
and they all crash with "Segmentation fault". 
The backtrace for gcc.dg/struct/wo_prof_mult_field_peeling.c is:

and so on (I can give similar ones for the other cases).  Note that if I remove
'-fipa-type-escape' the segfaults disappear (with unpatched rev. 131689).
