Public bug reported:
When executed via $PATH, ie
$ go
The command segfaults during an early mmap operation
futex(0x3fffabd2a49c, FUTEX_WAKE_PRIVATE, 2147483647) = 0
open("go", O_RDONLY|O_CLOEXEC) = 3
fcntl(3, F_SETFD, FD_CLOEXEC) = 0
mmap(NULL, 4096, PROT_READ, MAP_PRIVATE, 3, 0) = -1 ENODEV (No such device)
When executed with the full command line, ie
$ /usr/bin/go
Everything works and the command is hunky dory
open("/usr/bin/go", O_RDONLY|O_CLOEXEC) = 3
fcntl(3, F_SETFD, FD_CLOEXEC) = 0
mmap(NULL, 4096, PROT_READ, MAP_PRIVATE, 3, 0) = 0x3fff7c563000
munmap(0x3fff7c563000, 4096) = 0
/usr/bin/go is redirected via an alternative
