Hello,

Attached files are from gcc 9.1.0 but I've tested earlier and later versions
using https://godbolt.org/ with the same results.

Expected output:
1
1.000000
STRING
VECTOR

Actual output from 7.1 to 8.3:
VECTOR
VECTOR
VECTOR
VECTOR

Actual output from 9.1 and later:
Segmentation fault

Regards.
