Bug #71842 for Win32-IPHelper:

Even with the 0.007-fixed version of Win32::IPHelper, calling GetAdaptersInfo() in any way crashes Perl on a 64-bit Windows 2008 R2 system. Suspect another 64-bit value in there that's being treated as 32-bit. Using ActivePerl 5.12.4Build 1205 (64-bit) - claims to be built for MSWin32-x64-multi-thread The following event is produced in the Win event log: -------------- Faulting application name: perl.exe, version: 5.12.4.1205, time stamp: 0x4dfff767 Faulting module name: Iphlpapi.DLL, version: 6.1.7601.17514, time stamp: 0x4ce7c6da Exception code: 0xc0000005 Fault offset: 0x000000000000679c Faulting process id: 0x1278 Faulting application start time: 0x01cc90089e35983a Faulting application path: C:\Perl64\bin\perl.exe Faulting module path: C:\Windows\system32\Iphlpapi.DLL Report Id: dc844372-fbfb-11e0-a231-005056970063 -------------- Example minimum code to reproduce: use Win32; use Win32::IPHelper; my @ip_adapter_info; my $status = Win32::IPHelper::GetAdaptersInfo(\@ip_adapter_info); die sprintf("GetAdaptersInfo() error %u: %s\n", $status,Win32::FormatMessage($status)) unless ($status);
