Hi,

I have attached the gdb session output and .osc file.

Hi Igor,

I'll do that when I get back home (soon). The osc file is not too big, but it's not empty,  it has a few deleted nodes, updated ways and such.

thank you for the feedback. I have forgotten one thing in the instructions:

You need after the two print command the command

c

to le the program run to the next hit of the breakpoint. You can cycle through the three commands with keys up and then copy the whole session output at once.

Best regards,

Roland
