compile error (using clang with asan)

[frokaikan]

I use clang(with fsanitize=address) to compile this project.
when I call $ make
I receive:

awk -v l=/opt/SmallerC/v0100/srclib/ '/.$/{$0=l$0}{print}' /opt/SmallerC/v0100/srclib/lcds.txt > lcds.op
./smlrcc -SI /opt/SmallerC/v0100/include -I /opt/SmallerC/v0100/srclib @lcds.op

smlrcc, smlrl, n2f may do a few allocations which aren't freed before termination.
This isn't critical to operation of these programs as they aren't doing lots of allocations and deallocations that would potentially cause out of memory errors (due to depletion of free memory or address space fragmentation). And these programs do not operate continuously.
My simple recommendation is to not use ASAN. It's unlikely to find any problem worthy of attention. The compiler proper, smlrc, does not allocate memory dynamically as of now.

@frokaikan Any progress?

Ah, I let asan not detect the memory leak and now I could compile it.
Thanks.
