There is no problem with negative signs.  Is var_1 a large number?  Compare:

clear
set obs 1
gen x = -100
tostring x, gen(strx)
clear
set obs 1
gen double x = -123456789123456
tostring x, gen(strx)
tostring x, gen(strx) format(%17.0g)

If you -set trace on- on the -tostring- that fails, you will see it
appears to default to %12.0g format - which is too small in this case:

  - else {
  - local fmt "%12.0g"
  - local format `", "%12.0g""'
  - }
