When I start mlnet, it runs for ~5-10 minutes, then stops. Sometimes, it takes the computer with it.

I use MLDonkey 2.5-3 and tried a self-compiled version (options --disable-gui), the 586 binaries and the 486 binaries.
The machine is a 32MB Cyrix 6x86 with 62MB Swap space.
It runs on debian GNU/Linux 3.0 "woody", frequently dist-upgraded.

I tried to strace all versions. The strace looks like this:
write (73, "\3520,\243\320\342\26@\277\220\0j\0\210\3 \6`\31\340*M"..., 500) = 500
read (39, "\343\21\0\0\0xO\336\310\v\353\220\2160\364\t\27\\w\353"..., 500) = 500
munmap (0x41556000, 630784) = 0
munmap (0x415f0000, 561152) = 0
munmap (0x41776000, 561152) = 0
gettimeofday({1055197685, 777564}, NULL) = 0
gettimeofday({1055197685, 785649}, NULL) = 0
--- SIGSEGV (Segmentation fault) ---
getvlimit (0x3,0x833c934) = 0
rt_sigaction (SIGSEGV, {SIGF_DFL} NULL, 8) = 0
sigreturn () = 2 (mask now [])
--- SIGSEGV (Segmentation fault) ---
+++ Killed by SIGSEGV +++

Twice, on the compiled and the 586 binary, it happened after a gettimeofday(); in the 486 version, it happened after a read.
All of them have in common the SIGSEGV (Segmentation fault), which leads to the killing of the process.

Please contact me if you want me to commit other tests (like compiling it with trace options and running them).
