While using 5.1-RELEASE, I find that if my application program seg
faults, it produces "programname.core"; but it is 0 bytes.
I ran the exact same program on another machine that was running
4.4-RELEASE, and I do get a core file that I can use with gdb.
I'd really appreciate if someone could help me resolve this.
Additional details:
- It is not specific to the application program. I tried a 2 line program:
char p[8];
memcpy(p, "1234567890123456789012345678901234567890", 40);
with same results on 5.1-R(0 byte core file) and 4.4-R(usable core file)
- "ulimit -a" on the 5.1-R machine gives
core file size (blocks, -c) unlimited
- Just to be sure I used getrlimit() to find what the limit for
RLIMIT_CORE is in my processes, and it is RLIM_INFINITY.
- I did the basic checks like write permission on current directory, it
looks fine.
Can someone help me resolve this?
Thanks,
Yogeshwar.
