Tom> I will debug it today. Ok, I found the problem. "a" is defined in a system library for which I have debuginfo installed: (top-gdb) p *sym.symtab $22 = { [...] filename = 0x26ba950 "../sysdeps/ieee754/dbl-64/atnat.h", dirname = 0x26c4f10 "/usr/src/debug/glibc-2.14-34-ge2a3090/math", So the condition erroneously parses. Changing the names to "a_param" instead makes it fail again. I think the test is bogus, though, so I changed it in a way that will make it succeed. I can send a new revision of everything if you want. Tom
