[Seqan-dev] bug report readSequence()

<-- thread
<-- date
Dear all,

i recently upgraded sequan from 1.4.0 to 2.0.0. I did not change my code. 

When i now try to run the program  i get the following allocation error when i try to read a sequence via readSequence() from a FaiIndex:

/seqan/basic/basic_exception.h:368 FAILED!  (Uncaught exception of type std::bad_alloc: std::bad_alloc)

This error occurs only on my laptop with 4GB RAM. When i run the program on a Server with 500GB RAM - it works.

It seems that the memory that is allocated, for the string that the sequence is read in, is to high.

I appended the stacktrace from gnu debugger.  

Thanks in advance !
Eik
