Hi there,
I get a crash when doing "make check" for version 2.3.0 on Solaris Sparc.
The build was done with gcc 7.3.0.
The crash happens in ioloop-poll.c line 181 when running test_istream_multiplex.c:
#0 io_loop_handler_run_internal (ioloop=ioloop@entry=0x130dd0) at ioloop-poll.c:181 181 if (pollfd->revents != 0) {
Due to the code
180 pollfd = &ctx->fds[ctx->fd_index[io->fd]];
181 if (pollfd->revents != 0) {I can see in gdb, that io->fd is "-1", so using it as an array index doesn't make much sense:
(gdb) print io->fd $2 = -1
and the resulting address of pollfd is not valid. The full io struct is:
(gdb) print *io
$3 = {io = {condition = IO_READ, source_filename = 0x8c680
"test-multiplex.c", source_linenum = 84, pending = false, callback =
0x33c14
Full stack:
[Current thread is 2 (Thread 1 (LWP 1))]
(gdb) bt full

I unfortunately don't know, why the fd field is "-1".
Regards and thanks
