   Could anyone tell me if this happens on their systems?

   When I export LD_PRELOAD=libmalloc.so.1 on Solaris 9 and run dbx, it
crashes.

truss reports:
brk(0x1005DC150)                                = 0
     Incurred fault #6, FLTBOUNDS  %pc = 0xFFFFFFFF7F200FC8
       siginfo: SIGSEGV SEGV_MAPERR addr=0x00014000
     Received signal #11, SIGSEGV [default]
       siginfo: SIGSEGV SEGV_MAPERR addr=0x00014000

dbx version:
  Forte Developer 7 Dbx Debugger 7.0 Patch 115977-02 2004/04/07
(latest patch 115977-03 crashes as well)

This problem does not appear on Solaris 7 with dbx version:
  Sun WorkShop 6 update 2 Dbx Debugger 6.2 Patch 115117-01 2003/12/17

However dbx appears to run fine with any other malloc replacement
library (watchmalloc/bsdmalloc/mtmalloc).

Just want to make sure it's not some configuration issue on my end.

thanks,
Mike Morgan
