Hello, On a machine that has an old linux kernel, when valgrind 3.21.0 runs an executable that contains a call to syscall 378 - valgrind fails after being killed by a fatal signal.
The kernel on the machine is 3.10.0 x86_64 (the system is based on RedHad 5, I think), libc 2.17, and the executable itself is 32 bit. On this particular kernel, syscall 378 happens to be mapped to setprocns, while valgrind thinks that an executable is trying to execute syscall preadv2, which is indeed mapped to 378 on newer kernels, but doesn't exist in linux 3.10.0 Older versions of valgrind (for example, valgrind 3.10.0) don't have this problem, and succeed to execute the same executable on this machine. According to release notes it seems that this platform is supported. What can I do to fix the problem? Unfortunately I am stuck with having to use such an old system, and therefore using newer kernel is not an option. Test program and valgrind's report with the fatal signal are attached. gcc 6.3.0 was used for compilations (both the executable and the valgrind).
