The only time rpmbuild has died with a segfault for me was when I was packaging AVR32 libraries, and the internal dependency generator blew chunks when looking through the AVR32 ELF. I mention it because you seem to have taken some pretty unusual evasive actions %define __strip /bin/true If strip was causing you trouble (due to a non buildhost arch somehow?) then maybe the auto dep generation can do the same. My segfault went away by adding %_use_internal_dependency_generator 0 to my ~/.rpmmacros If that doesn't solve it, try running rpmbuild through strace, eg strace rpmbuild -ba mylib.spec and see what the last few things it touched were. -Andy
