Dear all,
while checking f951 for memory leaks on testcases that appeared
relevant during work on pr108924, I found that the conversion
warning triggered by do_subscript_6.f90 uses a code path that
forgot to mpfr_clear a used variable.
The attached obvious patch fixes this - verified by valgrind.
Pushed to mainline as r13-6344-g03c60e525bea13 .
Thanks,
Harald
