It was the SGI Fortran 90 compiler.  I haven't seen any reports of similar
problems with the SGI C or C++ compilers.

Regardless of the command syntax, is there a way of doing:

	(gdb) show pathmap
	some complex-jibberish is displayed
	(gdb) set pathmap jibberish

so that the entire path map can be set using a single command (instead
of having to construct it).

Hmm, Yes ok, the directory command doesn't have an equivalent:

(gdb) show directories
Source directories searched: $cdir:$cwd
(gdb) directory /tmp
Source directories searched: /tmp:$cdir:$cwd
(gdb) set directories $cdir:/tmp:/$cwd
No symbol table is loaded.  Use the "file" command.
[[this is an error ok :-)]]
(gdb) show directories
Source directories searched: /tmp:$cdir:$cwd
(gdb) 

:-(


If such an underlying mechanism then, I think, that would be more
useable GUI's (what to add to MI).  The CLI might then add a vineer that
included operations such as ``pathmap add''.

A regex operation sounds useful (if slightly more obtuse for non UNIX
die-hards).
