Compiling with mingw, fossil receives SIGSEGV in in sbsWriteText :
int x = strlen(p->zStart);
Printing zStart in gdb shows : $2 = 0x7 <Address 0x7 out of bounds>.
In the caller, we have:
s.zStart = "<span class=\"diffrm\">";
... /* nothing here modifies zStart */
sbsWriteText(&s, ...);
gdb details follow:
