[Bug 1309896] [NEW] perl dumps core in DBI->data_sources('mysql', { host => 'unresolvable' })
You have been subscribed to a public bug:
Perl seems to trip up on a bad munmap() when attempting to connect to an
unresoavlable host:
lasse@depravity:~$ perl -MDBI -e 'DBI->data_sources("mysql", { host => "unresolvable" })'
*** Error in `perl': munmap_chunk(): invalid pointer: 0x00007fffd31bb950 ***
Aborted (core dumped)
lasse@depravity:~$
A plain connect works:
lasse@depravity:~$ perl -MDBI -e 'DBI->connect("dbi:mysql:host=unresolvable")'
DBI connect('host=unresolvable','',...) failed: Unknown MySQL server host 'unresolvable' (0) at -e line 1.

The stacktrace seems to point to libdbd-mysql-perl as the culprit but I
guess it might as well be perl, libdbi-perl or libmysqlclient18...
