I retract "SIGSEGV everywhere". If I compile client.c with -O0, then
the third SIGSEGV is avoided, and I don't see any others.
Summary: olvwm runs on my system only if I make all three of these
changes, each of which avoids a SIGSEGV:
In cursors.c, remove (int) from this line:
st_insert(cursorTable, (int) p->name, (char *) p->num);
In image.c, #include "mem.h".
Compile client.c with -O0.
Alternatively, the first two SIGSEGVs (but not the third) can be avoided
by making no code changes but instead linking with -no-pie.
