0xb7471c20 in MysqL_send_query () from /usr/lib/libMysqLclient.so.15

我已经检查过驱动程序和数据库都是最新的(DBD::mysql 4.0008,MysqL 5.0.32-Debian_7etch6-log).

令人讨厌的是,我不能用一个简单的脚本重现这个：

use DBI;
use Test::More tests => 2;

my $dbh = DBI->connect( "dbi:MysqL:test",'root' );

sub test_db {
    my ($number) = $dbh->selectrow_array("select 1 ");
    return $number;
}

is test_db,1,"connected to db";

warn "restart db now";
getc;

is test_db,"connected to db";

这给出了以下内容：

ok 1 - connected to db
restart db now at dbd-MysqL-test.pl line 23.

DBD::MysqL::db selectrow_array Failed: MysqL server has gone away at dbd-MysqL-test.pl line 17.
not ok 2 - connected to db
#   Failed test 'connected to db'
#   at dbd-MysqL-test.pl line 26.
#          got: undef
#     expected: '1'

这行为正确,告诉我为什么请求失败.

让我感到困惑的是它是segfaulting,它不应该做.因为它似乎只在整个应用程序运行时发生(使用DBIx::Class),所以很难将其减少到测试用例.

我应该从哪里开始调试这个？有没有人见过这个？

更新：进一步的刺激显示它在mod_perl下是一个红鲱鱼.将它简化为一个简单的测试脚本我现在已发布到DBI mailing list.感谢您的回答.
