Current CVS sources are hard-broken for Linux :((
On my laptop with a 2.2.14 kernel, postmaster exits with a segfault, and
gdb fails to keep ahold of the image when running:
Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.
which will make it difficult for me to debug.
The tree worked yesterday. Philip, what exactly did you do to "cause the
configure test to fail"? Can I just go in a muck with Makefile.global?
I'd like to get up and running so I can finish testing and submit some
patches!
