user breakpoint called from code at 0x....

[Richard Hao]

Hi there,

Right now I have a problem when I debug my project.
Each time I start to debug my project (I do not set any breakpoint yet), a
message popup says "user breakpoint called from code at 0x77f762e8" which
shows in assembly code like "77F762E8 CC int 3" and I never set breakpoint
here.
When I hit "go" and it come to here again. I never reached the point I need
to look at.

Could someone help out here?

Thanks.

Either you've corrupted your program, or you have bad memory, or most
likely, your program is getting confused, and calling or jumping to some
random location. The processor then charges merrily along until it hits
something that makes it stop. A GPF is the commonest thing; you've hit a
different case.

Put breakpoints in at the top level of control in your program and
divide-and-conquer until you find the place where it goes mad.

Best of luck.

On Windows NT, when you launch a program under the debugger the OS uses a
special "debug heap". This heap will fire a breakpoint whenever it it
detects memory errors, including buffer overruns, underruns, double frees,
and writing to freed memory. Chances are that's what you're seeing here.
Look in the output window for the address of the allocation that was
corrupted.

If you want to ignore the problem (bad idea), launch the program outside of
the debugger and attach to it.

Installing the symbols for nt (specifically ntdll.dll) would help - the
callstack will show that it is in fact the heap manager -

I'll get you yet bazuzi boy
