    Hi,
  
  
     
  
  
    The ECPG preprocessor converts the code
  
  
    "static VARCHAR str1[10], str2[20], str3[30];"
  
  
    into
  
  
    "static  struct varchar_1  { int len; char arr[ 10 ]; }  str1 ;
  
  
             struct varchar_2  { int len; char arr[ 20 ]; }  str2 ;
  
  
             struct varchar_3  { int len; char arr[ 30 ]; }  str3 ;".
  
  
    Storage declaration applies only to the first structure.
  
  
     
  
  
    The patch in the attachment fixes the bug. Storage declaration will be repeated before each structure.
  
  
    The patch is on github too: https://github.com/andr-sokolov/postgresql/commit/c8f8fc7a211938569e7d46c91a428d8cb25b6f9c
