- If you indent the following code with gcc 4.2, by highlighting lines 06-10
and indenting, it confuses line 07 as the first line of a function rather than
the first line of a statement, and so everything is shifted left.
- If you move the preprocessor lines 02 and 04 back to column 1, it indents
correctly.
- If you change "#if defined(A)" to "#if 0" while still indented, it indents
correctly.
There is just something that cc-mode does not like about indented preprocessor
statements. 4.1 exhibited the same behavior, and prevents us from upgrading
from 23.4.
IMPORTANT: you MUST close and re-open the file between these tests because the
caching in cc-mode interferes with the results.
01 int f(void) {
02 #if defined(A)
03 printf("test\n");
04 #endif
05
06 if (test) {
07 int i = 0;
08 printf();
09 }
10 }
The source:
int f(void) {
#if defined(A)
printf("test\n");
#endif
if (test) {
int i = 0;
printf();
}
}
Thank you,
Kevin Burge

This appears to work correctly in Emacs 24.5.
