! I CC'd you on my response to Palle, but to spell it out, what you need

! 1. Remove the -march=pentium3 option.

Yes, thank You, this got clear to me in the afternoon.

Yes, -mstackrealign helps. So, as my local problem is now solved,
I am thinking about that "greater good for mankind" thing. ;)
At least one other person did run into the issue, and from Your
explanation I understand that this is not a postgres issue, but
could happen to any piece of software that decides to use gcc.
Now it seems easy to put this compiler option into the port's
specific makefile for postgreSQL, but it should actually be fixed
systemwide.
But, while it gets recommended to set the cpu-type systemwide on
FreeBSD, it is not recommend for the system owner to set CFLAGS
systemwide (even less specific ones for gcc - and I didn't find
a proper way to do that, anyway).
So my proposal is that this one belongs into /usr/ports/Mk/bsd.gcc.mk
+ .if ${MACHINE_CPU:Msse} && ${MACHINE_ARCH} == i386
+ CFLAGS+= -mstackrealign
+ .endif
That seems to work. Palle, Your opinion?
