Conventional wisdom tells that when malloc crashes the free list
(aka arena) has been trashed. This can happen eg. by a double free
(some malloc versions check against this) or by writing beyond the
end of a buffer.

You might want to try the following:
env MALLOC_CHECK_=1 vgcreate ...

This will use a debugging version of malloc which might print
sone diagnostics to stderr if a problem is encountered.

see malloc(3) for additional information.


Hope this helps
Michael
