Bug#521737: [alpha] Segfault in memchr when called via strstr

[Santiago Vila <sanvila@unex.es>]

Hi.

This seems to be the same bug that makes m4 1.4.14 test suite to fail on alpha.
The failed test is "test-strstr". Here is a backtrace:

#0  memchr () at ../ports/sysdeps/alpha/memchr.S:73
#1  0x00000200000db9f8 in two_way_short_needle (haystack_start=0x20000027ffc "aax", needle_start=<value optimized out>)
    at str-two-way.h:269
#2  *__GI_strstr (haystack_start=0x20000027ffc "aax", needle_start=<value optimized out>) at strstr.c:79
#3  0x0000000120000e48 in main (argc=1, argv=0x11ff245e8) at test-strstr.c:70
(gdb)   

Thanks.
