Hi,
My program sends answers in threads and runs the main MHD loop on
external event in an other thread and I get crashes. I'm suspecting
LMHD because valgrind point out that the memory for response is
used after free in a kind of race condition between internals of MHD.
Is it a known issue fixed
Hi José,
For sure you can run MHD with "external poll" mode, but you must ensure
that only single thread is calling MHD_run() at any given moment of time.
If you want to call several copies of MHD_run(), make sure that you have
individual copies of MHD for each thread (start MHD by
MHD_start

Okay, that is a good hint, thanks. I'm going to first track concur

You should replace (slow) valgrind with (fast) address-sanatizer.
Simply tell GCC (or clang) to compile with: -fsanitize=address -fno-
omit-frame-pointer

Okay, that is a good hint, thanks. I'm going to first track concurrent
use of MHD_run. FYI, I tried the late
