Description:
Having the most basic code to start embedded mysql server, same code works if it is being compiled as exe, and crashes if compiled in a DLL (called from DLL exported function).

For non-embedded server everything works OK either way.

How to repeat:
1. put some basic code for embedded server start in a exported DLL function
2. create exe that loads the DLL and calls this function
3. app crashes at embedded server initialisation

Suggested fix:
Perhaps some compilation flag? (since the same code works in exe)

I am unable to duplicate this using MySQL 4.0.16.  If testing against 4.0.16 does not resolve the issue, please submit a complete test case.

Thank you

I've tested again using v4.0.16 and the bug is still there.

I tested your test code against the latest bk 4.0 tree and
not crash happens. i added some lines of code for to print
before the return line.

E:\bug\test\test_fail\DbTestExe>DbTestExe
I am printing this before the return 0; code line
that means no crash :)
