[mpich-discuss] exit without calling finalize（windows xp pro 64bit）

[Jayesh Krishna]

Hi,
 Good to know you are able to narrow down on the problem. Try using a debugger to find the part of the code that fails.

Regards,
Jayesh

Hi,Jayesh

Just as what you say, there is something wrong with my code, rather than MPI. 
I removed the code with respect to MPI in the program, and run it again. Three hours later, an error which was not found in test phase occurred,
  Unhandled exception at 0x78078705 (msvcp100.dll) in xx.exe: 0xC0000005: Access violation writing location 0x00000000.

That means the issue has nothing to do with MPI.
Although the error has yet to been found, the problem has become less difficult. 

Thanks,
Junbo
