trying to debug latest release candidate of netcdf
I hit this SIGSEGV before reaching main
$ gdb .libs/ctest.exe
GNU gdb (GDB) Cygwin 7.9.1-1
.....
Reading symbols from .libs/ctest.exe...done.
(gdb) break main
Breakpoint 1 at 0x100401171: file

146 orq $0x0, (%rcx) /* probe there */
I thought it was a stack issue and I raised from 2M to 8M
SizeOfStackReserve 0000000000200000
SizeOfStackReserve 00000000007a1200
with no success.
May be it is not a netcdf bug ? Ideas what to look for ?
$ uname -svr
CYGWIN_NT-6.1 2.0.4(0.287/5/3) 2015-06-09 12:22
In addition there is a problem with gcc-debuginfo
$ cygcheck -l gcc-debuginfo |grep cygwin.S
/usr/src/debug/gcc-4.9.3-1/libgcc/config/i386/cygwin.S
