Re: ld cygwin crash

[Neil Phillips]

Hi,

The problem appears to only affect the binutils distributed with cygwin
(binutils-20040725-2), which is not the same as the official 2.15 release.

The offical 2.15 release builds and works correctly, however I had trouble
building the latest snapshot (041009).

The problem is present after building the cygwin version from source, which
results in the following,

----------------------------------------------------------------------------

the object file (test.o as described previously) produced by the official
and cygwin-modified gas is identicle.

This looks like a problem for the cygwin developers rather than the official
binutils.
