DS 3100/Xwindows bug

[Rod Stephens]

A guy I work with had a bug in a big Xwindows application on a
DECstation 3100. At link time he got a few pages of errors like:


/lib/libX11.a(Xrm.o): jump relocation out-of-range, bad object 
file produced, can't jump from 0x46c440 to 0x10003970 (index)
/lib/libX11.a(Xrm.o): jump relocation out-of-range, bad object
file produced, can't jump from 0x46c47c to 0x10003970 (index)
	:
	:
/lib/libc.a(getttyent.o): jump relocation out-of-range, bad object 
file produced, can't jump from 0x497614 to 0x10003970 (index)
*** Error code 1


After an unhelpful call to software support and much fiddling around,
he narrowed the problem down to a variable named "index". He changed
the variable's name to something else and all worked fine. It seemed
as if there might be some C language or system internal variable named
"index" and that his "index" was getting confused with this one.

Has anyone else seen this? Does anyone know what was happening?
