[Linux-ha-dev] segfaults when defined MARK_PRISTINE

[Pavol Gono]

Hi

I wanted to play with memory allocation a little.
I added #define HA_MALLOC_TRACK 1 in include/clplumbing/cl_malloc.h
and removed #undef  MARK_PRISTINE in lib/clplumbing/cl_malloc.c

After compilation the heartbeat processes segfaulted very soon with
this backtrace:
(gdb) bt

                                                                   #1

Is the macro MARK_PRISTINE considered to be unusable? Or shall I use
other configure options?

revision 10091, my configure options:
--with-group-name=haclient --with-ccmuser-name=hacluster
CFLAGS='-fno-unit-at-a-time -g -O0' --sysconfdir=/etc
--localstatedir=/var --disable-bundled_ltdl --disable-fatal-warnings
--disable-tipc --disable-ldirectord --disable-snmp --disable-mgmt
--disable-quorumd --disable-dopd --disable-static --enable-crm-dev

When I let the MARK_PRISTINE undefined, no segfaults.
