+riscv32 user mode emulation: fork return values broken
+
+When running in a chroot with riscv32 (on x86_64; qemu git master as of today):
+
+The following short program forks; the child immediately returns with exit(42). The parent checks for the return value - and obtains 40!
+
+gcc-10.2
+
+===============================================
+#include <stdlib.h>
+#include <unistd.h>
+#include <stdio.h>
+#include <sys/wait.h>
+
+main(c, v)
+     int c;
+     char **v;
+{
+  pid_t pid, p;
+  int s, i, n;
+
+  s = 0;
+  pid = fork();
+  if (pid == 0)
+    exit(42);
+
+  /* wait for the process */
+  p = wait(&s);
+  if (p != pid)
+    exit (255);
+
+  if (WIFEXITED(s))
+  {
+     int r=WEXITSTATUS(s);
+     if (r!=42) {
+      printf("child wants to return %i (0x%X), parent received %i (0x%X), difference %i\n",42,42,r,r,r-42);
+     }
+  }
+}
