This isn't the problem (these testcases are testing that we reject
coordinate systems which aren't valid, so these errors are expected and
correct).
The test failure seems to be actually due to the new PROJ4 ignoring
+vunits entirely and can be reproduced without involving Survex by
using cs2cs:
$ echo 36000 83000 5250|cs2cs +proj=tmerc +lat_0=0 +lon_0=13d20 +k=1 +x_0=0
+y_0=-5200000 +ellps=bessel
+towgs84=577.326,90.129,463.919,5.137,1.474,5.297,2.4232 +vunits=ft +to
+proj=tmerc +lat_0=0 +lon_0=13d20 +k=1 +x_0=0 +y_0=-5200000 +ellps=bessel
+towgs84=577.326,90.129,463.919,5.137,1.474,5.297,2.4232
36000.00 83000.00 5250.00
In older versions this converted the altitude from feet to metres, and
the output was:
36000.00 83000.00 1600.20
