Hi,
I am trying to debug the libuv test failures,
but it seems I am not able to convince GDB on stopping
just before the failure.

Is "thread apply all" working on Cygwin ?
The fact that produces no output in comparison to
a normal break command is a bit strange

(gdb) break test-dlerror.c:34
Breakpoint 1 at 0x10040b0b0: file 
/pub/devel/libuv/libuv-1.34.0/test/test-dlerro
r.c, line 34.
(gdb) thread apply all break test-dlerror.c:34

(gdb) run dlerror
Starting program: 
/cygdrive/d/cyg_pub/devel/libuv/libuv-1.34.0-build/test/.libs/

Any hint will be appreciated
