Congratulations on being able to solve the problem yourself!
It took me too long to figure out that the syntax errors I was getting
from lavaanC::lav_parse_model_string_c() were due to the invisible
U+00A0 (non-breakable space) characters from the e-mail. Once I ran
lav_parse_model_string_c(gsub('\ua0', ' ', model)) in a sanitized build
of R, I too saw the buffer overflow and a number of memory leaks.
Would you mind sharing with the list how you used address sanitizer
with R on Windows? Did you have to use the clang compiler, or have you
been able to use MSVC? Does Dr. Memory <https://drmemory.org/> find any
additional problems?
