But when= I simply configure glibc without mention of any specific Architecture like=20 ../glibc/configure --enable-debug --prefix=3D/usr then I am unable to repro= duce this failure. I suspect that the code generated is causing the issue 107 void 108 check_magic (int index, double value) 109 { 110 switch (index) 111 { 112 case 0: 113 TEST_VERIFY (value =3D=3D magic_values_double.v0); Assembly : 5d4: 7c 69 1b 78 mr r9,r3 - 5d8: 7f 64 db 78 mr r4,r27 + 5d8: 7b 64 00 20 clrldi r4,r27,32 -->generating this code fixes the issue 5dc: 38 60 ff ff li r3,-1 --=20 You are receiving this mail because: You are on the CC list for the bug.=
