Hey there!

I just filed web bug JI-9017423 (review id).
Just after I filed it, I noticed that all crash logs I received regarding this bug share a commonality. The VM region involved in the crash refers to a mapped .mp3 file. So they all look like this:

Exception Type:        EXC_BAD_ACCESS (SIGABRT)
Exception Codes:       0x000000000000000a, 0x000000018c4af000

VM Regions Near 0x18c4af000:
    mapped file            000000018c428000-000000018c4a0000 [  480K] rw-/rwx SM=COW  /System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Resources/English.lproj/Localized.rsrc
--> mapped file            000000018c4a0000-000000018c4cc000 [  176K] r--/r-x SM=PRV  /Volumes/VOLUME/*/*.mp3
    IOKit                  000000018c4e9000-000000018c51c000 [  204K] rw-/rw- SM=SHM 

And as a matter of fact, the part of the program in which the crash occurs, does parse through a bunch of .mp3 files.
So perhaps this is not a Hotspot problem after all, but a memory mapped file problem or a combination of both.

Could someone please attach this information to the bug report?

Thank you,
