I am not sure if purify can help here. Original message: http://www.hpc.uh.edu/fvwm/archive/0207/msg00373.html The is a memory violation in function paint_menu which is file menus.c about line 4100. This violation occurs randomly, which doesn't make it easier ;-), when using dynamic menus together with mutliple menu styles. As far as we found out yet there are two lines in paint_menu where a voilation occurs. Those two may or may not caused by the same problem. Common is both locations that the pointer sequence mr->s->ms is accessed. In my last mail I posted the values of this three pointers shortly before the crash. The second case I described shows that the contents of mr->s->ms point to a wrong location. The first case I described seems a little bit odd to me since the three pointers seem to have proper values. Even I had a look in menus.h where the struct MenuRootStatic is described. In this stucture there is a declaration Pixel sideColor; before the declaration MenuStyle *ms;. If the pointer *ms is overwritten by accident it may be done by a overflow in this sideColor variable. To check this one could insert a char array between the two declaration and watch this. If this is the case the overflow will affect the char array which otherwise should be never accessed. If nothing comes out in this case today I will probably do this at weekend.
