| From http://bugreports.qt.nokia.com/browse/QTBUG-8365 |
| |
| Starting a QtEmbedded-4.6.2 application linked against uClibc 0.9.30.1 results |
| in an immediate segmentation fault. |
| This is due to an incompatibility of the uClibc with the standard libc about |
| the "realpath" function. The man of the function clearly specifies that |
| "if resolved path (the second argument) is NULL, then realpath uses malloc to |
| allocate a buffer ...". However, uClibc doesn't support this functionality and |
| issues a warning at compile-time when the function is called with a NULL |
| argument. |
