Re: libthread fresh findings

[Justin Langer]

hai,

I tried to run the Hello-World Translator Multi-threaded version. (hello-mt.c).
I got the pgm from cvs.

hurd~# settrans -ac test hello-mt

But the program is crashing when a file system request comes (cat or
ls -l)in. The error caught with gdb is:

Program Received Signal
EXC_BAD_INSTRUCTION
Illegal Instruction/Operand in cthread_fork_child () from /lib/libthreads.so.0.2

---------------------------------------------------------------------
This is the same error i got with a Translator which I wrote with libnetfs.

---------------------------------------------------------------------

I think there is some problem some where? Can any _HURD_DEVELOPER_ help
me in fixing it? I think its prob with libraries....or.....

Is it because of Muli threading?

The function ports_manage_port_operations_multi_thread()? 

In both cases (hello-mt) and translator I wrote using libnetfs a bt gives:

#0 0x......  cthread_fork_child() from /lib/libthreads.so.0.2
#1 0x......  alloc_stack() from /lib/libthreads.so.0.2

#9 0x......  main(argc=x,argv=xxxx) at mypgm
#10 0x......  __libc_start_main() from /lib/libc.so.0.2

Can any one solve this stuff???
