I'm getting a segfault when running the latest tip compiled with gcc
4.8.4 on Ubuntu 14.04 and I've bisected it to this commit.
# gcc --version
gcc (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4
I'm configuring with:
# ./configure \
--static \
--disable-gtk \
--target-list=aarch64-softmmu
When run under gdb, I get:
Program received signal SIGSEGV, Segmentation fault.
buffer_find_nonzero_offset_ifunc () at ./util/cutils.c:333
333 {
(gdb) bt
#0 buffer_find_nonzero_offset_ifunc () at ./util/cutils.c:333
#1 0x0000000000939c58 in __libc_start_main ()
#2 0x0000000000419337 in _start ()
I confess I don't understand the intricacies here, but I'm willing to
test fixes if you have any ideas for how to make this also work for my
compiler without blindly excluding all gcc < 4.9.
