I cross-compile so build machine is:
NetBSD 8.1_STABLE (GENERIC) #0: Fri Jan 24 18:50:19 UTC 2020 mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64
Target machine is:
NetBSD 8.1_STABLE (7248-132.v6) #11: Sat Feb 22 00:36:53 MST 2020 XXXX@XXXX:/usr/obj/prep/netbsd-8/objdir/sys/arch/prep/compile/GENERIC prep
>Description:
Enabling the option "RESIDUAL_DATA_DUMP" in the prep kernel config will cause this error when compiled:
--- residual.o ---
/usr/src/sys/arch/prep/prep/residual.c: In function 'large_vendor_pcibridge_subr':

for (j = 0, first = 1, t = tmpstr; j < MAX_PCI_INTRS; j++) {

*** BUILD ABORTED ***
This looks like the commit that caused it:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/prep/prep/residual.c.diff?r1=1.16&r2=1.17&only_with_tag=MAIN&f=h
I'm by no means an expert in c, so someone might want to take a quick look and see if preceding for loop actually needs to use the t pointer or could be reworked like the changed for loop. A quick fix is to just add the t pointer back in.
>How-To-Repeat:
Enable kernel option in port-prep:
options RESIDUAL_DATA_DUMP # verbosely dump residual data
