SIGABRT on using Milu with sqlite.c

[vrthra]

I took sqlite3 current version (linked), created an amalgamated sqlite3.c, passed through gcc -E, and fed it into Milu as described in Readme. I added all functions in https://www.sqlite.org/c3ref/funclist.html in the func.txt, and executed below

./bin/milu -f func.txt sqlite3.c

I get SIGABRT (coredump analysis from gdb)

ERROR:src/mutation/ASTPrinter.c:1254:print_source_expr: code should not be reached

Program received signal SIGABRT, Aborted.
