The test C programe.
use gcc-3.3.3 to compile.
Created attachment 111438 [details]
make file for the test case.
Works for me just fine:
rpm -q --qf '%{name}-%{version}-%{release}.%{arch}\n' glibc; ./test 8388608; ldd
./test
glibc-2.3.2-95.30.i686
try to set stacksize to 8388608
soft limit for stack size=10485760
hard limit for stack size=4294967295
exit normally.

Make sure: 1) you have i686.rpm glibc installed, not the i386.rpm one
2) you don't have LD_ASSUME_KERNEL set in the environment
Non-FLOATING_STACK LinuxThreads really doesn't allow a thread stack larger than
2MB, as stack slots in that case are in fixed 2MB array. But that library never
supported bigger stacks. The i386.rpm glibc includes only this library,
but if your CPU is i686+, that's not what you should have installed.
Also, LD_ASSUME_KERNEL=2.4.0 and down to 2.2.5 selects that library even in
i686.rpm glibc, but then again, this is for compatibility with broken apps and
you should only set that env var for the app that reallly needs it, not for all
other apps as well.
I'm assuming you were using non-FLOATING_STACK LinuxThreads. If not, please reopen with details. Yes, by using the correct 'i686' package my problem is gone. Our sys admin wrongly installed a 'i386' package on a i686 machine, that cause this wired behaviour. Thanks. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: The attached program shows that it will fail to "setstatcksize" to over 2M. Please also note, that it only happened on glibc-2.3.2-95.30(the one we recently upgrade), but NOT on glibc-2.3.2-95.6. Version-Release number of selected component (if applicable): glibc-2.3.2-95.30 How reproducible: Always Steps to Reproduce: 1.do a "make" to compile the files, 2.on a "glibc 95.30" machine, run "./test 2097152", (2M), you should see "exit normally"(OK). 3.on a "glibc 95.30" machine, run "./test 2097153", (any >2M number), you should see "Error in set stack size" error msg.(FAILED!!) 4.on a "glibc 95.6" machine, run "./test 2097153", (or any other number), you should see "exit normally"(OK). Expected Results: I expect on all machine, I can set some large stack size, say 8M or even bigger. Additional info: I already try to "unlimit stacksize", but no luck.
