Hi,
Thank you, Hideki IWAMOTO and Shigio YAMAGUCHI.
The version of flex on my mac is 2.5.35 so I guess global/gtags is build
using that.
I rebuild global/gtags with YY_BUF_SIZE 65536 and that indeed
helped. Now I can generate tag files for system.api.php as well as the
rest of Drupal.
Best regards,
Arne
