Hi all!
I've never used DJGPP before, so I tried the 'Hello World' program to
get started:
-----------
#incllude <stdio.h>
void main()
 {
   printf("Hello World!\n");
 }
------------
The first time I run it with gdb 'run' command everything goes OK. But
if I exit gdb and try to launch it once more I get this:
---------
Starting program c:/djgpp/test/hello

Program received signal SIGSEGV, Segmentation fault.
<hex number> in <function name>
---------
After 3-5 'run' attempts (without exiting gdb) suddenly my 'Hello'
executes! If I reboot and try again, the result is the same - it works
for the first time and then causes errors. And if I try to run gdb
immediately after compiling, I get theese segmentation faults from the
very beginning - not a single successful run! It looks as if CWSDPMI
leaves in memory something that causes GDB malfunction. It's strange.
I use 486DX, 4Mb, DJGPPv2, GDB 4.12, CWSDPMI not resident, tried
booting clean (only the needed environment and path set).
Is there any way to restart the debuggee without leaving gdb? Any
comments would be appreciated.
Thanks in advance.
