Found it. It only occurs with -mcpu=cortex-a8: ~/linaro/toolchains/gcc-4.7~svn182617-armv7l-natty-cbuild220-tcpanda05-cortexa9r1/bin/g++ -O2 -c -g -mfpu=vfpv3-d16 -mcpu=cortex-a8 lp910791.ii The fault occurs in r178025, 178624, 182152, 182780 but not in 177688 so it was introduced somewhere between 177688 and 178025. Assuming the bug is in config/arm then it could be 177689 (rsandifo), 177705 (ramana), 177759 (ramana), 177852 (ramana), 177855 (rsandifo), 177891 (jye2), or 177902 (ams). I'm suspicious of 177759.
