Thanks, @Jesse. I ran the sample through strace and (among others) it logged something like this:
open("/lib/Plugins/liborbbec.so", O_RDONLY|O_CLOEXEC) = 4
read(4, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0(\0\1\0\0\0\0\213\0\0004\0\0\0"..., 512) = 512
lseek(4, 454476, SEEK_SET) = 454476
read(4, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 1240) = 1240
lseek(4, 454146, SEEK_SET) = 454146
read(4, "A4\0\0\0aeabi\0\1*\0\0\0\0057-A\0\6\n\7A\10\1\t\2\n\3\f"..., 53) = 53
fstat64(4, {st_mode=S_IFREG|0777, st_size=668638, ...}) = 0
mmap2(NULL, 497404, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 4, 0) = 0xb68c4000
mprotect(0xb692f000, 32768, PROT_NONE) = 0
mmap2(0xb6937000, 16384, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 4, 0x6b000) = 0xb6937000
mmap2(0xb693b000, 9980, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0xb693b000
close(4)
I attach the whole trace file (31.3 KB) in case it is of any help.
