Thank you all, and thank you Lazzar, I appreciate it.

what you adviced I have tried before, it is something like this

Quote:
onyx-bridge 13% blockMesh
Segmentation fault (core dumped)
onyx-bridge 14% gdb
GNU gdb 6.6

This GDB was configured as "mips-sgi-irix6.5".
(gdb) core core
Core was generated by `blockMesh'.
Program terminated with signal 11, Segmentation fault.
warning: wrong size gregset struct in core file
warning: wrong size gregset struct in core file
#0 0x00000000 in ?? ()
(gdb)
And I dont know what do these warning and error really mean!


And another question, is there a subforum for sgi-IRIX under this forum?

maybe you could try with dbx instead gdb if it is installed.
in dbx you type 'where' instead of 'bt' to get the backtrace.

MySQL Bugs: #25344: Segmentation violation when try to run the perror utility
the above link shows a case where gdb didn't work, but dbx showed a useful backtrace on irix.

Thank you Lazzar, that helps.
With dbx I have found a little bit more information than gdb.
However, I am still very frustrated, for the dbx show me as if something wrong with a *.C file, however, there's no problem at all when I compile it under any linux, that is to say, it shouldn't have to be the problem.

So, I doubt whether dbx have given me the right information!!!

CFD codes is extremely huge! I will keep on looking.

Best Regards,
Daniel
