--- Comment #6 from Andreas Schwab <sch...@linux-m68k.org> ---
On m68k it crashes here:
Program received signal SIGSEGV, Segmentation fault.
__GI_memcmp (s1=0x0, s2=0x0, len=2285895680) at memcmp.c:333
333 memcmp.c: No such file or directory.
(gdb) up
#1 0x8000093c in std::char_traits<char>::compare (p3=<optimized out>,
p2=<optimized out>) at ../gcc/testsuite/g++.dg/pr77550.C:221
221 return __builtin_memcmp(0, p2, p3);
With the change in #c5 it runs successfully.
