[jira] Commented: (HARMONY-2798) [drlvm] VM cunit test test_native_basic sometimes crashes on win32 SMP

Salikh Zakirov commented on HARMONY-2798:
-----------------------------------------

Strangely, I wasn't able to reproduce the issue on Windows Server 2003sp0 on a HT Pentium 4.
The test worked in the loop for a day, and did not fail once in 7908 iterations.

> The test test_native_basic fails on windows from time to time in 3 different ways. The most common way is to exit silently on shutdown while function main has returned 0, and all tests passed. Two other ways are access to non-writable memory and MS debug CRT heap validation on shutdown.
> In all 3 cases I cannot debug the program because it fails after function main has finished. Looks like some race condition causes memory corruption. Probably running the program from under VS.NET could help to debug it.
> To run the test many times I've written the following script in cygwin bash:
> i=0; while true; do ./test_native_basic.exe -Dorg.apache.harmony.vm.vmdir=d:/work/harmony/enhanced/trunk/working_vm/build/win_ia32_msvc_debug/deploy/jdk/jre/bin/default -Djava.home=d:/work/harmony/enhanced/trunk/working_vm/build/win_ia32_msvc_debug/deploy/jdk/jre; ec=$?; echo $i $ec; test $ec != 0 && break; i=$[i+1]; done
> Note, to run test_native_basic in console you need to set PATH to DRLVM bin and bin/default directories.
> Note2, it looks like this bug requires SMP or at least HT enabled system, and is not reproducible on single processor computers like laptops.
