[Pkg-osm-maint] Bug#766770: imposm-parser: Segmentation fault in OSMPBF.so

[Nelson A. de Oliveira]

Source: imposm-parser
Version: 1.0.5-1
Severity: important
Tags: upstream patch

Hi!

We have found that imposm-parser is deadlocking while processing PBF files,
due to a segmentation fault in OSMPBF.so:

=====
Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x00007f20cfdd0378 in Way_dealloc (self=0x7f20bfc02030) at imposm/parser/pbf/osm.cc:4318
4318          delete self->protobuf;
=====

It's already reported upstream for more than 1 year (but without any
answer lately):
https://github.com/omniscale/imposm-parser/issues/9

Yesterday, Jocelyn was able to debug it and kindly provided a patch:
https://github.com/omniscale/imposm-parser/pull/13

We have stress-tested imposm-parser with this patch and we don't see any
problem anymore (it always succeed now, while before we were having
problems on 25% of the runs, sometimes)

It would be good to have this applied on Debian, even if it's not yet
accepted on upstream.

Thank you!

Best regards,
Nelson
