MySQL crash with custom parser
Posted by: Clement Ho

I am using MySQL Community version 5.1.20-beta. It is running in a Windows 2k3 64-bits system. I wrote a custom parser which is only “,” is the delimiter. The parser is in .dll format. It works fine initially. However, after running for a little while, I would hear a beep from the machine. Then Database stop to any query request, Update, Insert or Delete.
I have to kill the MySQL process from task manager and start the service again.
Does anyone has this problem happen to him? I don’t know if it is my code in the custom parser or it is the bug in MySQL.
Thanks.

PS I have more information on this crash. I have VStudio 2005 running on the crashing server. here is the stack of the crash:

ntdll.dll!7d620dce()
[Frames below may be incorrect and/or missing, no symbols loaded for ntdll.dll]
ntdll.dll!7d620ea5()
ntdll.dll!7d620fbe()

mysqld-nt.exe!my_lock(int fd=4128768, int locktype=0, unsigned __int64 start=238209332554055672, unsigned __int64 length=4112138270107844600, int MyFlags=957431800) Line 57 C
> mysqld-nt.exe!free(void * pBlock=0x4d10f904) Line 103 C


And the above is from C:\Program Files (x86)\Microsoft Visual Studio 8\VC\crt\src\free.c


Does anyone out there what is happening? I am having the same problem since 5.1.19-beta.
