The current source (CVS or 3.1.1, same) of XaoS (http://xaos.sf.net), if you compile it and run bin/xaos, gives a segmentation fault if you press the button B twice (setting perturbation on/off). Now if I add the following line to src/ui-hlp/menu.c in the end of uih_persw():
printf(""); there will be no segfault. Do you think this is a gcc problem? (However, other statements may solve the problem, not only printf(). I also tried sync() with success.) I'm using SuSE 9.1 (but the same problem occurs on 9.0, too, with an earlier gcc version). However, I'm not an expert in C programming. But this seems to be odd that a virtually uneffective printf("") can solve a segfault problem. I never experienced such an odd behaviour earlier in gcc. -- Summary: odd behaviour compiling XaoS Product: gcc Version: 3.3.3 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: kovzol at math dot u-szeged dot hu CC: gcc-bugs at gcc dot gnu dot org GCC host triplet: (uname -a) Linux d7017 2.6.4-54.5-default #1 Fri May 7 21:43:10 GCC target triplet: (gcc --version) gcc (GCC) 3.3.3 (SuSE Linux) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19873
