Some time ago, I posted a question regarding twm crash. I was not able to reproduce it after, but I don�t played more than a few minutes. Later, some one told me that twm is inherently weak, and pointed me to fvwm. My concern was mainly because I am new to X Windows, and I was fearing regarding my build of XFree86 4.2.0 ( even if all went ok with make World after two or three minor hacks ). I build and intend to use it on a QNX 4.25 platform which has some departures from a standard *NIX: lack of UNIX sockets ( only INET ) and lack of shared libraries. Also, because other questions I build the whole thing using register calling convention. So, the crash of twm troubled me. But it must be noted that the crash happened after some time of execution, not at the very start.
