Ooh... Further on, I'm betting the "+++ killed by SIGABRT (core dumped) +++"
shouldn't be there:
[pid 32452] poll([{fd=3, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=3,
revents=POLLOUT}])
[pid 32452] writev(3, [{iov_base="b\0\4\0\6\0@\4", iov_len=8},
{iov_base="RENDER", iov_len=6}, {iov_base="\0\0", io
v_len=2}], 3) = 16
[pid 32452] futex(0x7fffd1f3f468, FUTEX_WAIT_PRIVATE, 0, NULL <unfinished ...>
[pid 32493] +++ killed by SIGABRT (core dumped) +++
<... futex resumed> ) = 0
futex(0x2982778, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x2a27454, FUTEX_WAKE_PRIVATE, 1) = 1
futex(0x2a27400, FUTEX_WAKE_PRIVATE, 1) = 1
futex(0x2a3e7d8, FUTEX_WAKE_PRIVATE, 1) = 1
write(5, "\1\0\0\0\0\0\0\0", 8) = 8
read(8, "\372", 1) = 1
poll([{fd=5, events=POLLIN}, {fd=8, events=POLLIN}], 2, 0) = 1 ([{fd=5,
revents=POLLIN}])
read(5, "\7\0\0\0\0\0\0\0", 16) = 8
write(5, "\1\0\0\0\0\0\0\0", 8) = 8
poll([{fd=3, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=3, revents=POLLOUT}])
writev(3, [{iov_base="+\0\1\0", iov_len=4}], 1) = 4
futex(0x7fffd1f3e3d8, FUTEX_WAIT_PRIVATE, 0, NULL) = 0
futex(0x2982778, FUTEX_WAKE_PRIVATE, 1) = 0
write(5, "\1\0\0\0\0\0\0\0", 8) = 8
brk(0x51c1000) = 0x51c1000
