However if I try the same with csint.f90 that's produced I get a different set
of error messages but not the same failure. Slightly bizarre.

That looks like fixed-form source input. Try to compile with -ffixed-form or
use the .f file extension.

Works for me with a cross to arm-linux-gnueabi and -O -mhard-float
-march=armv7-a -mthumb -mfpu=vfpv3-d16 (not sure if that replicates gnueabihf).
 Also works
with a cross to arm-linux-gnueabihf for me:

rguenther@murzim:/abuild/rguenther/obj-arm-g/gcc> ./f951 -quiet t.f90 -O

This has been fixed by the r208926 fix (PR60697), the backtrace is the same as
well.

CCing Vlad whether we want to just add the testcase to the testsuite and close,
or close without testcase, or whether this PR was just a different bug that
just went latent with that fix.

I'll close this as a dup.  If we want the testcase, we can add it afterwards.
