It looks like there's some timing problem in terms of stderr output. I
just made up the example for the Cygwin ML discussion about the mcmodel.
When I start the code built with -mcmodel=small I expected the output:
Cygwin runtime failure: /home/corinna/dll/main.exe: Invalid relocation.
Offset 0xfffffffd80348989 at address 0x40000103b doesn't fit into 32 bits
However, no output was generated at first run, and not at second:
---
$ ./main
$ ./main
$
---
Then I started ssh, and suddenly the messages appeared. They
even appeared at the right spot:
---
$ ./main
Cygwin runtime failure: /home/corinna/dll/main.exe: Invalid relocation.
Offset 0xfffffffd80348989 at address 0x40000103b doesn't fit into 32 bits
$ ./main
Cygwin runtime failure: /home/corinna/dll/main.exe: Invalid relocation.
Offset 0xfffffffd80348989 at address 0x40000103b doesn't fit into 32 bits
$ ssh
[...]

Very puzzelling.
