Interesting bug.
I think one needs to read 9.4.5.4 that defines
the interpretation of blanks as BLANK=NULL, and
10.7.6 which I think means your string should
be seen as (note there are 2 space before
each REAL).

As mentioned here:

Just building a simple: int main(void) { return 0; }

That doesn't mean this bug isn't fixed. It is. There are just additional
issues, during var-tracking, in particular PR43051.

Confirmed. I am not sure if this fits Wconversion but it is something subtle
that would be nice to detect.
The testcase should be:
#include
unsigned val1 = 0x1000, val2 = 0x100;
int main(int argc, char **argv)
{
With the following code:
INTEGER :: someint
CHARACTER (LEN=40) :: strcounter
WRITE(strcounter,'(I)') someint
The error message is generated:
WRITE(strcounter,'(I)') someint
1
Error: Nonnegative width required in format string at (1)
Which to me just suggests

You're welcomed. With my suggested fixes, you'll actually
have standard conforming code.

Do you intend math, mfh, mth, and nsp to be of type integer or real?
The following works:
character(len=200) :: str
real :: x,math,mfh,mth,nsp
str = ' 4.38000+ 6 2.55100+ 0 4.5+ 6 2.51970+ 0 5.0+ 6 2.400
