malloc: *** error for object 0x1029249b0: pointer being freed was not allocated

Question

I'm trying to compile a program which contains -std=c++0x on a mac OS X 10.6.8 with xcode 3.2.6. I upgraded my g++ compiler to g++-4.7 with homebrew. In my makefile I changed the lines from:

CXX          = g++
CXXFLAGS     = -std=c++0x
LD           = g++
LDFLAGS      = -L.

to:

CXX          = g++-4.7
CXXFLAGS     = -std=c++0x
LD           = g++-4.7
LDFLAGS      = -L.

however, this line wasn't working:

$(CC) -c -Icore/include/ -Ianalysis/include -Ieventbuilders/include -Isimdut/include -Istyle/include $(CXXFLAGS) $< -o $@

so I changed it to:

$(CXX) -c -Icore/include/ -Ianalysis/include -Ieventbuilders/include -Isimdut/include -Istyle/include $(CXXFLAGS) $< -o $@

everything now compiles, but when I run my file I get the following error:

tbmon(25203) malloc: *** error for object 0x1029249b0: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap

Could someone please advise me what I've done wrong? Thank you in advance!

Answer 1

You've got a bug in the program where it calls free() on a pointer that wasn't obtained with malloc() . Or some other memory-related bug in the code that triggers this behavior.

Make files you have provided are not related to this problem. You have to fix the program code.

Answer 2

Just changing the compiler from, presumably, gcc to g++ shouldn't cause free(3) to fail. Could you please post a minimal example demonstrating the issue?
