gtags behaves strange when parsing code with the right curly brace in #else clause.

[刘洋]

Hi,

My gtags behaves strange when parsing this code:

  1 #define FOO

  2 

  3 int foo1()

  4 {

  5     if (1)

  6     {

  7 #ifndef FOO

  8 #else

  9     }

 10 #endif

 11     return 1;

 12 }

 13 

 14 int foo2()

 15 {

 16     return 1;

 17 }

The function foo2 was ignored:

$ gtags --verbose

[Wed Aug 05 21:32:12 CST 2015] Gtags started.

[Wed Aug 05 21:32:12 CST 2015] Creating 'GTAGS' and 'GRTAGS'.

 [1] extracting tags of test.c

[Wed Aug 05 21:32:12 CST 2015] Done.

$ gtags -d GTAGS

 __.COMPNAME __.COMPNAME

 __.COMPRESS __.COMPRESS ddefine ttypedef

 __.VERSION __.VERSION 6

FOO 1 @n 1 address@hidden @n

foo1 1 @n 3 int @n()

My gtags version is 6.5:

$ gtags --version

I think it's the same error when gtags parsing MySQL sql_parse.cc at line 1983 to line 2002.

All functions after line 2001 was ignored.

I'm sorry that my English is poor. If you need more information, please let me know.

Thanks for your hard on GNU global!
