can you provide your binary?

or at least objdump around address
0x00007f69e30e075c - 0x7f69e30b9000 = 0x2775c

objdump -rdw |grep -C 100 '2775c:'

make the context (-C) large enough so we see the function
entry, a proper backtrace would be useful too (e.g.
looking at the coredump from gdb).

disabling syscalls with EPERM is a chrome bug,
but this issue seems independent.
