Hi Owen and others,
Thanks! I have tried using the memprof 5.1 (preloaded on RH 9.0) with
some glib applications.
Most glib applications run fine, except the multi-threaded ones. I
have found that when I use memprof on a multi-threaded glib
applications, the application simply hangs at the g_thread_create().
My system is RH 9.0 and is using pthread.
If I use memprof on the below application, it stops right after
"Creating thread1" is displayed.
Is it a known issue? Any workaround?
Sorry, no, it's not a known issue to me; I last tested threaded apps
around August 2002, and it was working then with whatever libc version
I was running, but new libc versions very frequently do break memprof
for various and sundry reasons.
One thing you might try just as an experiment is to:
export LD_ASSUME_KERNEL=2.2.5
This will disable NPTL and force a fallback to the older LinuxThreads
implementation which might not trigger the same problem.
Regards,
Owen
