While trying to build 2.37 for debian I noticed a
strange build failure: the debian/clisp.substvar file
contained NULL characters.
After investigating a little I found that 2.37 won't
append correctly to this file, while 2.36 will.
I made no changes from the last 2.36 release, nor are
there changes w.r.t the 2.37 tree.
I've attached a straight typescript, and strace output
extract for 2.36 and 2.37.
