Re: Crash of mysql under cygwin with g++ 3.3.1

[Fabrice Marchal <fmarchal at inf dot ethz dot ch>]

Hallo Gerrit,

late reply too.

I guess from your message that you used a version of mysql server
compiled under cygwin. I downloaded and installed 4.0.17 and I still
have the bug with the latest cygwin and that server. I'll try with your
compiled version.
Thanks
Fabrice
