#5 Memory fault under HP/UX when sending email

[Kurt Andersen]

Having built Ishmail 1.9.12 as documented in my previous bug report, I am finding that *whenever*
I send a message (using the send/close button), Ishmail emits the message and then core dumps
before closing the window.

[Kenneth Herron]

I'm experiencing similar behavior, although not every time I send mail. In my case, ishmail is receiving a signal while in a memory-allocation routine; the signal handler calls another function which tries to call another memory-allocation function. The mem-allocation routines aren't reentrant so this causes a crash.

Could you use a debugger to produce a backtrace from the core file? I'd like to rule out the possibility that your problem is from something else.

Try to recompile hgl/HalAppC.C and hgl/MemMap.C with -DHPUX and see if it makes any change.

[Kurt Andersen]

Rebuilding hgl/HalAppC and hgl/MemMap with -DHPUX did *NOT* fix the problem.

Here's the backtrace from the core dump. I've rebuilt the entire Ishmail tree with -DHPUX.
