Also confirmed present in GHC 7.2.2 on CentOS 5 with error message 

*** glibc detected *** test: double free or corruption (out): 0x0000000017e744f0 ***
*** glibc detected *** test: corrupted double-linked list: 0x0000000017e744c0 ***

Error does not occur if built with "-rtsopts" and run with "+RTS -N -A4m -H128m -G5"
