            Bug ID: 113587
           Summary: Compile error with #pragma (end)region
           Product: gcc
           Version: 13.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: liavonlida at gmail dot com
  Target Milestone: ---

I tried GCC 13.1 and got a compile error with valid code.

Mininal sample is:

void f()
{
#pragma region Shape
        if (true)
        {
        } 
#pragma endregion Shape
        else if (true)
        {
        } 
}

result is:
<source>: In function 'void f()':
<source>:9:25: error: 'else' without a previous 'if'
    9 |                         else if (true)
      |                         ^~~~

It's fine with:
GCC <= 12 and MSVC

GCC 13 and later (trunk) fails on it.
