Dear Plan 9 fan,
I have some trouble with alef's
par control statement.
Everything works fine
with two statements in the par block.
The program core dumpes, if there are
more statements in the par block.
Can you help me?
Hans-Peter
-----------------------------------------------
The source code, an example for a execution of the program,
some 'ps | grep par_test' lines, and some debugger information
follows.
The source:
--------------------
/* par_test.l */
#include <alef.h>
void main(void)
{
int index;
print("pid = %d\n", getpid());
for ( index = 0; index < 200; index ++ )
{
par
{ print("@");
print("#");
print("X");
}
}
}
Execution:
--------------------
term% file p*t
par_test: sparc plan 9 executable
term% par_test
pid = 1899
@par_test 1901: suicide: sys: trap: fault write addr=0xfffffff8 pc=0x10f0
X
Where is prozess with the pid 1900?
Ps info:
--------------------
term% ps -aux | grep par_test
none 1899 1:10 0:00 76K Ready par_test # cpu
none 1901 0:00 0:00 76K Broken par_test
term% ps -aux | grep par_test
none 1899 1:18 0:00 76K Ready par_test # time grows
none 1901 0:00 0:00 76K Broken par_test
Debugger:
--------------------
term% db 1901
sparc binary
last exception: data access exception
par_2.l:12 main+#d0? MOVW R10, #4(R8)
$c
