I'm getting a strange error while rebuilding iproute-2.6.9-3.EL4.3.centos4.src.rpm ...

rpmbuild --rebuild iproute-2.6.9-3.EL4.3.centos4.src.rpm ... ./normal >normal.dist *** glibc detected *** free(): invalid next size (normal): 0x08491050 *** /bin/sh: line 1: 5236 Aborted ./normal >normal.dist make[1]: *** [normal.dist] Error 134 ... + install -m 644 tc/normal.dist tc/pareto.dist tc/paretonormal.dist /data/tmp/cd654c/rpm/tmp/iproute-2.6.9-root/usr/lib/tc install: cannot stat `tc/pareto.dist': No such file or directory install: cannot stat `tc/paretonormal.dist': No such file or directory error: Bad exit status from /data/tmp/cd654c/rpm/tmp/rpm-tmp.36741 (%install) ... etc.

Any ideas as to what might be causing this heap corruption?

I'm using a pretty much stock CentOS 4.3 box to perform the rpm rebuild.

Running the "normal" binary under gdb doesn't provide much additional info:
