Subject: [Bug libc/13276] assertation failure in realloc when running out of virtual mappings
Date: Sat, 08 Oct 2011 20:01:00 -0000	[thread overview]
Message-ID: <bug-13276-131-k65Ydns3hx@http.sourceware.org/bugzilla/> (raw)

--- Comment #4 from Rich Felker <bugdal at aerifal dot cx> 2011-10-08 20:01:30 UTC ---
I can't reproduce the failure for realloc (calling realloc to resize a
mmap-sized block down to size 1 results in mremap to PAGE_SIZE rather than
servicing it from the heap), but I was able to reproduce it with free instead
of realloc. Test case is attached.
