hop of those help? gfx points to an object in stack. Are you sure that the object is still there (at the same position where it was) when you are trying to draw?

What can cause segmentation faults in C++?


By : Android_Android

I wish did fix the issue. Segmentation fault is caused by bad accesses to memory, only if your OS has a MMU (Memory Management Unit). Otherwise, you won't get it but only strange behavior.
The virtual memory (the entire memory accessible to you = 2^(sizeof(pointer_type)*8) (ie: 2^num_bits_in_pointer_type)) is mapped to physical memory in units named pages or segments (paging superseded segmentation but they are still used).

segmentation faults in MPI-2

around this issue any idea why the following would give me a segfault? , Since the signature of MPI_Bcast is this:
code :
int MPI_Bcast(
  void *buffer,
  int count,
  MPI_Datatype datatype,
  int root,
  MPI_Comm comm
);
MPI_Bcast(buf_int, 12, MPI_INT, 0, MPI_COMM_WORLD);

I wish did fix the issue. As indicated in a comment, the issue is now resolved thank to a bugfix by the Z3-team (closed bug report). This bugfix was integrated in the next released version, Version 4.4.1, which at the timing of writing is the latest.

Segmentation faults in JNA/BridJ etc

like below fixes the issue I've rebuilt my Java/C++ project several times using JNI, JNA, BridJ, and JavaCPP, and every time I encounter random (unpredictable) segmentation faults. I have verified that a pure-C++ executable using this library never causes segmentation faults, and in the case of BridJ, narrowed it down to Java's garbage collector by explicitly invoking it. , The quick fix:
code :
export LD_PRELOAD=/path/to/libjsig.so
gSystem->ResetSignals();
