Hello:
Back to the patch#866 problem I'm having. I'm using vim 7.4.1416:
* using efence: links fine, but won't run (runs out of memory)
* using valgrind: works
* using valgrind --leak-check=full: works
As can be seen from the trace below, the program hangs in a call to
nanosleep
in mch_delay(). The parameters to the nanosleep call seem to me to be
correct.
I put in the following code in mch_delay to force HAVE_USLEEP at line 632:
#undef HAVE_NANOSLEEP
#ifndef HAVE_USLEEP
# define HAVE_USLEEP
#endif
This, too, "fixes" the problem. I wrote a small program which exercises
nanosleep with the same time delay (5ms) and it doesn't hang. So, its
not clear to me whether there's a vim source bug, a compiler bug, or o/s
bug.
So: is there a configure option to disable HAVE_NANOSLEEP?
Regards,
Chip Campbell
