Description Graham Dennis 2003-10-01 04:27:17 UTC 
Version:           3.0.0a7 (using KDE 3.1.9)
Compiler:          gcc version 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r1, propolice)
OS:          Linux (i686) release 2.4.22-ck2

Steps to reproduce:
insert the code into the file
#define GMT1_1_2001       978307200
#define UNIX2OSX(x)   ((x)-GMT1_1_2001)

#undef GMT1_1_2001
#undef UNIX2OSX

Now begin to type UNIX2OSX( ... on the opening parenthesis it SEGFAULTS
This bug is always reproducible. Gideon was built using KDE3.2alpha2 but I found the same problem with KDE3.1.4 and a previous release of gideon.
Comment 1 Graham Dennis 2003-10-01 04:28:57 UTC 
Forgot to mention: 
Workaround: Comment out the #undef
Comment 2 Amilcar do Carmo Lucas 2003-10-03 19:13:06 UTC 
A backtrace would be nice!!!
Comment 3 Graham Dennis 2003-10-05 10:58:52 UTC 
I rebuilt it with debugging enabled, but the backtrace isn't that large... (but larger than 
before) perhaps I've done something wrong. But this bug is reproducible for any #define 
#undefined function... Not just the one mentioned in my initial report.

sorry, but we can't reproduce it, maybe it is a bug of your distribution
