Recently I've changed my environment (about 6000 from 8192 bytes used),
and now I'm encountering a bug when starting gdb or fsdb.

I've recompiled fsdb with debug info - here is what symify says:

Exiting due to signal SIGSEGV
General Protection Fault at eip=00018c85
eax=00000001 ebx=0000117e ecx=00000004 edx=000000af esi=0006b394 edi=00001100
ebp=0006624c esp=0006623c cs=00a7 ds=00af es=00c7 fs=008f gs=00bf ss=00af
Call frame traceback EIPs:
  0x00018c85   ___dj_movedata+33
  0x00011696   _v2loadimage+1106, line 145 of v2load.c
  0x00001823   _main+403, line 129 of ed.c
  0x00012993   ___crt1_startup+115

It works fine when I unset most of my environment (like 2000 from 8192).


BTW, is someone working with a huge environment > 16 kB ?
Does this cause troubles with the usual programs (size of the
transfer buffer) ?
