I recently startet getting the below error = 2.4.2 and trunk, so
probably not fpc.
But The particular code in Lazarus hasn't changed (from what it was
before I start getting the error)
If I step into it, then fpc_ansistr_concat get's 2 perfectly valid
strings (as far as I can see). Tha code is even in a loop , it works 3
or 4 times, then boom.
The issue is, I am at loss, where to even start looking. So any hints
will be welcome...
It happens if I run the gdb test case in lazarus= my version is
currently modified from the one in svn, but the debugger code, that
crashes is not modified.
