Do you know if thread 1 is, maybe detached?
If so, has it already exited (but hasn't been joined yet?)
Also what does coreinfo say?

Subject: Problem debugging core dump

4.7.1 (with 6.4.1 tools)

I load a core dumpe file. It has 4 thread and the first one did the SIGSEGV.  But in the debug view I cannot see thread 
1.  Only the 3 other thread.

If I go in the debugger console I can type command, such as thread 1 and look for the info I want, so it's there alright
.

I setup the gdb console in verbose mode and noticed the following output

13 info tidinfo
&"info tidinfo\n"
~"Threads for pid 1834197100 (D:\\ide-4.8.0-workspace\\logc\\scanners\\depro_lc\\obj6\\depro_lc.exe)\nTid:\tState:\
tFlags:\n"
~" 4\t4\t1\n"
~" 3\t4\t1\n"
~"*2\t4\t1\n"
~" 1\t0\t129\n"

I find it suspicious that thread 1 is the one with a state and flags diffierent then the other 3.

This is happening on every core dump I check ( they all have threads )

Thanks

That means thread has exited and dead threads are not shown in IDE. The 
question is why debugger shows it as dead if you say this is the thread 
that got SIGSEGV

I ran into the same problem with IDE 4.7.0 and QNX 6.5.0 (x86).

I contacted support and a bug report has now been filed as PR 92167.
