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 - Ajit
