To Reproduce
Steps to reproduce the behaviour:

1. have a text file (test.out) with this content:

==17727==ERROR: LeakSanitizer: detected memory leaks

Direct leak of 7 byte(s) in 1 object(s) allocated from:
    #0 0x49c2ad in __interceptor_malloc /projects/compiler-rt/lib/asan/asan_malloc_linux.cpp:129:3
    #1 0x4ce525 in main files/lsan2.c:5:9

Direct leak of 5 byte(s) in 1 object(s) allocated from:
    #0 0x49c2ad in __interceptor_malloc /projects/compiler-rt/lib/asan/asan_malloc_linux.cpp:129:3
    #1 0x4ce543 in main files/lsan2.c:7:16

SUMMARY: AddressSanitizer: 12 byte(s) leaked in 2 allocation(s).

2. report-converter -t lsan -o report ./test.out
3. See error:
   [INFO] - No 'lsan' results can be found in '...'

Expected behaviour
report-converter found a leak

Hi,

Make sure that files/lsan2.c relative path is valid relative to the current working directory when report-converter is executed. I also created a patch to solve this issue.

[bruntib]

Sorry, closed accidentally. I didn't mean to close it until the patch is merged.

[Katze719]

Oh, thanks for letting me know. I wasn't aware that the report-converter requires access to the source files.

[bruntib]

Actually, report-converter doesn't require access to these files, but almost all other CodeChecker commands do. For this reason my first thought was printing a comprehensible error message, why report-converter didn't generate any reports and still abort report generation. I chose this current solution, because this way "CodeChecker parse" can provide some statistics at least. But all other CodeChecker commands will emit an error message.
