Am seeing intermittent crashes in function Perl_stashpv_hvname_match.

System is ActivePerl version 5.8.8.820\, on Windows Server 2003 Enterprise x64 Edition.

Two stack traces are below.

Please advise how best to proceed.

Thank you for any assistance.

You didn't show your code\, you didn't indicate which modules were loaded\, you didn't indicate anything about whether you're using any threading features or the Win32 pseudo-fork feature. Providing any of those might help. Contacting ActiveState would also be reasonable since its their build.

I'm immediately suspecting some corrupted data because of either bad thread usage or maybe just some buggy XS/C code. Based on where in the code you were probably in av_store\, I guess you were writing to some kind of tied variable. I also guess there's muckery afoot in the object backing the tied variable.

Its all 100% speculation though.

From mbuxbaum@digital-strata.com

More info concerning this crash bug in Perl which I logged a week ago on Mar 13 2007.

Both times this crash occurred the Perl was processing large data files- over 500MB for the first\, and over 1GB for the second.

Note that I could not reproduce the crash a third time using the first data file.

There may be a memory- or size-related factor.

I’m going to assume this is the same bug I fixed in the 5.15.x series related to the current package being freed (due to *{__PACKAGE_."::"} = *whatever) and then subs being defined.
