linux 64 core dump issue (gcc 3.4.3 and gcc3.4.6)

[Bhat, Ajit]

Hi -

We recently upgraded compiler from to 3.4.3.
We are facing core dumps if we try to run gcc 3.4.3 built binaries on gcc 3.4.6 machine. 
The stack trace we have is -
#0  0x0000003468f2e21d in raise () from /lib64/tls/libc.so.6
(gdb) where
#0  0x0000003468f2e21d in raise () from /lib64/tls/libc.so.6
#1  0x0000003468f2fa1e in abort () from /lib64/tls/libc.so.6
#2  0x0000003468f63291 in __libc_message () from /lib64/tls/libc.so.6
#3  0x0000003468f686b2 in malloc_consolidate () from /lib64/tls/libc.so.6
#4  0x0000003468f68c3a in _int_free () from /lib64/tls/libc.so.6
#5  0x0000003468f691f6 in free () from /lib64/tls/libc.so.6
#6  0x0000003468f30c69 in exit () from /lib64/tls/libc.so.6
#7  0x0000003468f1c402 in __libc_start_main () from /lib64/tls/libc.so.6
#8  0x0000000000584a8a in _start ()

We are not sure if there are any incompatibility issues between those two gcc version. I have attached patches on the target machine.

Appreciate any help.


Thanks and Regards
