I have a Tcl library compiled with nedmalloc and when I link
against it and make
#define MemAlloc Tcl_Alloc
#define MemFree Tcl_Free
it runs fine.
Yes, please

bash-2.03$ gcc -O3 -o tcltest tcltest.c -lpthread -DNDEBUG -
DTCL_THREADS -I/usr/local/include -L/usr/local/lib -ltcl8.4g
bash-2.03$ gdb
gdb may slow down concurrency, does it run without gdb, also does it run
with solaris malloc?

I was suspecting Linux malloc, looks like it has problems with high
concurrency, i tried to replace MemAlloc/Fre with mmap/munmap, and it
crashes as well.
#define MemAlloc mmalloc
#define MemFree(ptr) mfree(ptr, gSize)
void *mmalloc(size_t size) { return
yes, it crashes when number of threads are more than 1 with any size but
not all the time, sometimes i need to run it several times, looks like
it is random, some combination, not sure of what.
I guess we never got that high concurrency in Naviserver, i wonder if
AOL has randomm crashes.

I converted all to use pthreads directly instead of Tcl wrappers, and
now it does not crash anymore. Will continue testing but it looks like
Tcl is the problem here, not ptmalloc

I have no idea, i spent too much time on this still without realizing

Right, with Ns_ functions it does not crash.

Not at all!
So, I would like to know exactly how to reproduce the problem
(what OS, machine, etc).
Furthermore I
