As maintainer of TeX Live for openSuSE I've run on a problem with eptex
dumping platex.  During beta test we always set some environment variables
in our build system like MALLOC_CHECK_=3 and MALLOC_PERTURB_=69.  With
this I see in the logs as well as in a clean chroot build environment:

 eptex -ini  -jobname=platex -progname=platex \*platex.ini
 This is e-pTeX, Version 3.1415926-p3.2-110415-2.3 (utf8.euc) (TeX Live 2011) (INITEX)
 restricted \write18 enabled.

 Here is how much of TeX's memory you used:
  4131 strings out of 498426
  56505 string characters out of 3222515
  47789 words of memory out of 3500000
  3394 multiletter control sequences out of 15000+200000
  3640 words of font info for 14 fonts, out of 3000000 for 9000
  745 hyphenation exceptions out of 8191
  21i,0n,20p,263b,76s stack positions out of 5000i,500n,10000p,200000b,50000s
 No pages of output.

No if I do

 unset MALLOC_PERTURB

the dump works flawless. But IMHO there is a problem with a possible
memory curruption due access to freed memory ... or simply a missing
memset(.., 0, ..).
