Syslinux - Apr 2010 - remote gdb & com32

Hey guys,

  I've searched the archives but couldn't find any instructions on
setting breakpoints in
com32 apps. I'm trying to debug my app under Qemu. BTW, is there any
limits on the
amount of malloc space you can do? I'm trying to track down a reboot
after a lot of
mallocs.

Thanks a lot.

Under Qemu you can connect via the Qemu gdb stub interface.  Load the
symbol table from the .elf file which is created during the build process.

mallocs are limited by available system memory, minus a megabyte or two.

If you are using QEMU on Windows, there is a serious bug with GDB and TCP.
