[lazarus] Lazarus crash on Win32

[Horacio Jamilis]

Ok,

What i found:

in astrings.inc - procedure PChar_To_AnsiStr - line 266:

print a -> $8 = (PCHAR) $0

print p -> $6 = (PCHAR) $a918

x/s p -> $a918:    <Address $a918 out of bounds>

print p[0] -> Error: Cannot access memory at address $a918

any hint?

Horacio
