Paul,
could you please make sure configure added "-D_REENTRANT" to the CFLAGS ?
/* otherwise, errno is a global variable instead of a per thread
variable, which can
explains some weird behaviour. note this should have been already fixed */
assuming -D_REENTRANT is set, could you please give the attached patch a
try ?
i suspect the CLOSE_THE_SOCKET macro resets errno, and hence the
confusing error message
e.g. failed: Error 0 (0)
FWIW, master is also affected.
Cheers,
Gilles
