Hello,

I'm trying to spawn a program (which is not a DJGPP executable) and
wait for it to exit using spawnvpe as such:

-----
#include <stdlib.h>
#include <process.h>

int main(int argc, char * argv[], char **envp)
{
     char *args[] = {
       "prog.exe",
       0
     };
     
     spawnvpe(P_WAIT, "prog.exe", args, envp);
}
-----

It runs "prog.exe" correctly, but hangs on exit of the program.

Bash also fails, but in a different way.  On return from "prog.exe",
bash gets a general protection fault with this dump:

General Protection Fault at eip=482f3; flags=3046
eax=00000300 ebx=00000021 ecx=00000000 edx=00000000 esi=00181780 edi=0016b28c
ebp=0016b134 esp=0016b128 cs=a7 ds=af es=b7 fs=bf gs=bf ss=af error=00ec

I looked up 0x482F3 in bash.exe and it is an "int 0x31" insruction.
I'm not very familiar with DOS and DJGPP programming, so any help is
appreciated.  I come from a UNIX background, so it was nice to find
BASH for DOS!.

BTW, I'm using bash1147 and gcc-2.951.

Thanx,

-Dave
