[Mono-dev] Problem with mcs build

Sun Oct 9 23:22:15 UTC 2016

Finally got back to this. Added gdb to the mono-wrapper script and got the
following:

Temporary breakpoint 1, main (argc=24, argv=0x7ffffff188) at
./main.c:213                   213             mono_build_date =
build_date;                                               (gdb)
stepi

9610            return field->offset;
