Jakub, will it be possible for you to add me to CC list for every issue opened for ia32el ? Thanks, Yoav. this problem will be fixed with version 88.34.22, which is currently under validation. should be ready early next week. Created attachment 107923 [details]
a patch to fix the problem
Should be fixed in ia32el-1.1-12 in dist-4E-lacd, also put to ftp://people.redhat.com/jakub/ia32el/ I tried ia32el-1.1-12. It doesn't work well.
This ia32el outputs the elf32 core dump file of a 32bit multi-threads
process but the process doesn't finish. ps(1) shows that its status is
'T(stopped)'.

Thanks,
We could not reproduce the failure. On which OS version did your run the test ? Was it pre RC1 ? Also - is it the same test that was used in the first report ? If not - can we have the sources of the new test ? Thanks, Yoav. > On which OS version did your run the test ? Was it pre RC1 ?
Yes, OS version is RHEL4 pre RC1 and I use the same test program.
But I compile the test program on RHEL4 beta1 for i386 or RHEL3 U3 for
i386. Is it a problem?

Thanks,
the root cause of this problem is that traced threads cannot be killed. we opened a bugzilla for that - #143073, and marked it as a dependency. thanks, yoav. I'm taking this out of Modified, as it still appears to be an issue and the dependency isn't resolved either. Add RHEL4-L3support team in Japan Can we get a status update on this issue? Fujitsu is requesting a fix for this and the associated blocker bz 143073. Fujitsu team: please be sure to open an Issue tracker noting this BZ and the problem. That is now the process to use to track these items. Refer to Issue 66086. No longer seeing issues with ia32el-1.2-3.ia64 and kernel-2.6.9-6.37.EL. Moving to PROD_READY. |
Description of problem: A 32bit multi-threads application on IA32LE hungups while its core dump file is being output. Version-Release number of selected component (if applicable): ia32el-1.1-8 How reproducible: always Steps to Reproduce: 1. Compile the following source on RHEL4 for i386 # cc test-thread-core.c -o test-thread-core -lpthread -D_REENTRANT ------< source >----------------- // test-thread-core.c #include <stdio.h> #include <pthread.h> pthread_t tids[10]; void *__func(void *param) { int *p, *q; printf("Thread %d is started.\n", pthread_self()); sleep (5); p=0; *q=*p; return; } main() { int i=0, ret; for (i = 0; i < 5; i++) { ret = pthread_create(&tids[i], NULL, __func, NULL); if (ret != 0) { perror("Thread creation failed"); exit(1); } } for (i = 0; i < 5; i++) { ret = pthread_join(tids[i], NULL); } return; } ------< source >----------------- 2. Copy the compiled 32bit application to RHEL4 for ia64 3. Run the application on IA32EL # /etc/init.d/ia32el status # ulimit -c unlimited # file test-thread-core # ./test-thread-core Actual results: # /etc/init.d/ia32el status Intel IA-32 Execution Layer in use # ulimit -c unlimited # file test-thread-core test-thread-core: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), not stripped # ./test-thread-core Thread 1085852592 is started.
