• Labels: segmentation_fault

Description

Segmentation fault in getPooledString after call to 'createSPE'.

---------------------------------------------------------------------
...
// This string hasn't been seen before. Add it to the pool.
*pspe = spe = createSPE(in, fDoc);
return spe->fString;
}
---------------------------------------------------------------------

Reproducible in my environment unless built with debugging symbols (-d).

Steps to reproduce:

• build xerces-c_2_7_0 on AIX 6.1 with IBM XL C/C++ for AIX, V10.1 (32 or 64 bit)
• build sample programs
• execute for example CreateDOMDocument to get segfault

$dbx -d 10000 -C core
Type 'help' for help.
[Object file is not specified. Using "CreateDOMDocument" as an object file]
