#48 call graph crashes on mac

[Anonymous]

when I try to use the call graph, the system crashes with the following error message:

Why can a program run by you not create any directories/files in your own home directory?
This seems to be a missconfiguration on your side?

You can argue that KCachegrind should not crash in that case, but give a nice error.
But as it needs to create a dot file for the callgraph view to work, you would not
be able to see anything anyway.

Hmm... did you compile this on your own? Perhaps there is a problem with the KDE
library? You can try to compile qcachegrind instead (in subdirectory qcachegrind),
using Qt only (compile with "qmake;make").

I compiled qcachegrind on my mac without problems (qmake -spec 'macx-g++' ; make).
However, the generated app "qcachegrind" crashes on running with the following error:

Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000008

etc.etc.

It could be a problem with the Qt 4.8 library?
